New kind of variable star discovered

NGC 3766Astronomers using the Swiss 1.2-meter Euler Telescope at the European Southern Observatory’s La Silla Observatory in Chile have found a new type of variable star. The discovery was based on the detection of very tiny changes in brightness of stars in a cluster. The observations revealed previously unknown properties of these stars that defy current theories and raise questions about the origin of the variations.

The Swiss are justly famed for their craftsmanship when creating extremely precise pieces of technology. Now a Swiss team from the Geneva Observatory has achieved extraordinary precision using a comparatively small 1.2-meter telescope for an observing program stretching over many years. They have discovered a new class of variable stars by measuring minute variations in stellar brightness.

The new results are based on regular measurements of the brightness of more than 3,000 stars in the open star cluster NGC 3766 over a period of seven years. They reveal how 36 of the cluster’s stars followed an unexpected pattern: They had tiny regular variations in their brightness at the level of 0.1 percent of the stars’ normal brightness. These variations had periods between about two and 20 hours. The stars are somewhat hotter and brighter than the Sun but otherwise apparently unremarkable. The new class of variable stars is yet to be given a name.

This level of precision in the measurements is twice as good as that achieved by comparable studies from other telescopes — and sufficient to reveal these tiny variations for the first time.

“We have reached this level of sensitivity thanks to the high quality of the observations, combined with a very careful analysis of the data,” said Geneva Observatory’s Nami Mowlavi, leader of the research team, “but also because we have carried out an extensive observation program that lasted for seven years. It probably wouldn’t have been possible to get so much observing time on a bigger telescope.”

Many stars are known as variable or pulsating stars because their apparent brightness changes over time. How the brightness of these stars changes depends in complex ways on the properties of their interiors. This phenomenon has allowed the development of a whole branch of astrophysics called asteroseismology, where astronomers can “listen” to these stellar vibrations, in order to probe the physical properties of the stars and get to know more about their inner workings.

“The very existence of this new class of variable stars is a challenge to astrophysicists,” said Sophie Saesen, another team member. “Current theoretical models predict that their light is not supposed to vary periodically at all, so our current efforts are focused on finding out more about the behavior of this strange new type of star.”

Although the cause of the variability remains unknown, there is a tantalizing clue: Some of the stars seem to be fast rotators. They spin at speeds more than half of their critical velocity, which is the threshold where stars become unstable and throw off material into space.

“In those conditions, the fast spin will have an important impact on their internal properties, but we are not able yet to adequately model their light variations,” explained Mowlavi. “We hope our discovery will encourage specialists to address the issue in the hope of understanding the origin of these mysterious variations.”

An anarchic region of star formation captured

NGC-6559The Danish 1.54-meter telescope located at the European Southern Observatory (ESO) La Silla Observatory in Chile has captured a striking image of NGC 6559, an object that showcases the anarchy that reigns when stars form inside an interstellar cloud.

NGC 6559 is a cloud of gas and dust located at a distance of about 5,000 light-years from Earth in the constellation Sagittarius the Archer. The glowing region is a relatively small object, just a few light-years across, in contrast to the 100 light-years and more spanned by its famous neighbor, the Lagoon Nebula (M8). Although it is usually overlooked in favor of its distinguished companion, NGC 6559 has the leading role in this new picture.

The gas in the clouds of NGC 6559, mainly hydrogen, is the raw material for star formation. When a region inside this nebula gathers enough matter, it starts to collapse under its own gravity. The center of the cloud grows ever denser and hotter until thermonuclear fusion begins and a star is born. The hydrogen atoms combine to form helium atoms, releasing energy that makes the star shine.

These brilliant hot young stars born out of the cloud energize the hydrogen gas still present around them in the nebula. The gas then re-emits this energy, producing the glowing threadlike red cloud seen near the center of the image. This object is known as an emission nebula.

But NGC 6559 is not just made of hydrogen gas. It also contains solid particles of dust made of heavier elements such as carbon, iron, or silicon. The bluish patch next to the red emission nebula shows the light from the recently formed stars being scattered — reflected in many different directions — by the microscopic particles in the nebula. Known to astronomers as a reflection nebula, this type of object usually appears blue because the scattering is more efficient for these shorter wavelengths of light.

In regions where it is very dense, the dust completely blocks the light behind it, as is the case for the dark isolated patches and sinuous lanes to the bottom left-hand side and right-hand side of the image. To look through the clouds at what lies behind, astronomers would need to observe the nebula using longer wavelengths that would not be absorbed.

The Milky Way fills the background of the image with countless yellowish older stars. Some of them appear fainter and redder because of the dust in NGC 6559.

Herschel discovers some of the youngest stars ever seen

Youngest-starsAstronomers have found some of the youngest stars ever seen, thanks to the Herschel Space Observatory, a European Space Agency (ESA) mission.

Observations from NASA’s Spitzer Space Telescope and the Atacama Pathfinder Experiment (APEX) telescope in Chile, a collaboration involving the Max Planck Institute for Radio Astronomy in Germany, the Onsala Space Observatory in Sweden, and the European Southern Observatory in Germany, contributed to the findings.

Dense envelopes of gas and dust surround the fledging stars known as protostars, making their detection difficult. The 15 newly observed protostars turned up by surprise in a survey of the biggest site of star formation near our solar system, located in the constellation Orion. The discovery gives scientists a peek into one of the earliest and least understood phases of star formation.

“Herschel has revealed the largest ensemble of such young stars in a single star-forming region,” said Amelia Stutz of the Max Planck Institute for Astronomy. “With these results, we are getting closer to witnessing the moment when a star begins to form.”

Stars spring to life from the gravitational collapse of massive clouds of gas and dust. This changeover from stray cool gas to the ball of super-hot plasma we call a star is relatively quick by cosmic standards, lasting only a few hundred thousand years. Finding protostars in their earliest, most short-lived and dimmest stages poses a challenge.

Astronomers long had investigated the stellar nursery in the Orion Molecular Cloud Complex, a vast collection of star-forming clouds, but had not seen the newly identified protostars until Herschel observed the region.

“Previous studies have missed the densest, youngest, and potentially most extreme and cold protostars in Orion,” Stutz said. “These sources may be able to help us better understand how the process of star formation proceeds at the very earliest stages, when most of the stellar mass is built up and physical conditions are hardest to observe.”

Herschel spied the protostars in far-infrared, or long-wavelength light, which can shine through the dense clouds around burgeoning stars that block out higher-energy, shorter wavelengths, including the light our eyes see.

The Herschel Photodetector Array Camera and Spectrometer (PACS) instrument collected infrared light at 70 and 160 micrometers in wavelength, comparable to the width of a human hair. Researchers compared these observations to previous scans of the star-forming regions in Orion taken by Spitzer. Extremely young protostars identified in the Herschel views but too cold to be picked up in most of the Spitzer data were further verified with radio wave observations from the APEX ground telescope.

“Our observations provide a first glimpse at protostars that have just begun to ‘glow’ at far-infrared wavelengths,” said Elise Furlan from the National Optical Astronomy Observatory in Tucson, Arizona.

Of the 15 newly discovered protostars, 11 possess red colors, meaning their light output trends toward the low-energy end of the electromagnetic spectrum. This output indicates the stars are still embedded deeply in a gaseous envelope, meaning they are very young. An additional seven protostars previously seen by Spitzer share this characteristic. Together, these 18 budding stars constitute only 5 percent of the protostars and candidate protostars observed in Orion. That figure implies the very youngest stars spend perhaps 25,000 years in this phase of their development, a mere blink of an eye considering a star like our Sun lives for about 10 billion years.

Researchers hope to document chronologically each stage of a star’s development rather like a family album, from before birth to early infancy, when planets also take shape.

“With these recent findings, we add an important missing photo to the family album of stellar development,” said Glenn Wahlgren from NASA Headquarters in Washington, D.C. “Herschel has allowed us to study stars in their infancy.”

Rare triple quasar found

triple-quasarFor only the second time in history, a team of scientists, including Michele Fumagalli from the Carnegie Institution for Science in Washington, D.C., has discovered an extremely rare triple quasar system.

Quasars are extremely bright and powerful sources of energy that sit in the center of a galaxy, surrounding a black hole. In systems with multiple quasars, the bodies are held together by gravity and are believed to be the product of galaxies colliding.

It is difficult to observe triplet quasar systems because of observational limits that prevent researchers from differentiating multiple nearby bodies from one another at astronomical distances. Moreover, such phenomena are presumed to be rare.

The team led by Emanuele Farina of the University of Insubria in Como, Italy, combined observations from the New Technology Telescope of the European Southern Observatory at La Silla, Chile, and from the Calar Alto Observatory in Spain with advanced modeling. This enabled them to find the triplet quasar, called QQQ J1519+0627. The light from the three quasars has traveled 9 billion light-years to reach us, which means the light was emitted when the universe was only a third of its current age.

Advanced analysis confirmed that what the team found was, indeed, three distinct sources of quasar energy and that the phenomenon is extremely rare.

Two members of the triplet are closer to each other than the third. This means that the system could have been formed by interaction between the two adjacent quasars, but was probably not triggered by interaction with the more-distant third quasar. Furthermore, no evidence was seen of any ultraluminous infrared galaxies — galaxies with strong emission in infrared light — which is where quasars are commonly found. As a result, the team proposes that this triplet quasar system is part of some larger structure that is still undergoing formation.

“Honing our observational and modeling skills and finding this rare phenomenon will help us understand how cosmic structures assemble in our universe and the basic processes by which massive galaxies form,” Fumagalli said.

“Further study will help us figure out exactly how these quasars came to be and how rare their formation is,” Farina said.

Capturing the "wings" of the Seagull Nebula

Seagull-Nebula-wingThis new image from the European Southern Observatory (ESO) shows a section of a cloud of dust and glowing gas called the Seagull Nebula. These wispy red clouds form part of the “wings” of the celestial bird, and this picture reveals an intriguing mix of dark and glowing red clouds, weaving between bright stars. This new view was captured by the Wide Field Imager on the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile.

Running along the border between the constellations of Canis Major the Big Dog and Monoceros the Unicorn in the southern sky, the Seagull Nebula is a huge cloud mostly made of hydrogen gas. It’s an example of what astronomers refer to as an HII region. Hot new stars form within these clouds, and their intense ultraviolet radiation causes the surrounding gas to glow brightly.

The reddish hue in this image is a telltale sign of the presence of ionized hydrogen. The Seagull Nebula, known more formally as IC 2177, is a complex object with a bird-like shape that is made up of three large clouds of gas: Sharpless 2-292 forms the “head”; this new image shows part of Sharpless 2-296, which comprises the large “wings”; and Sharpless 2-297 is a small, knotty addition to the tip of the gull’s right “wing”.

These objects are all entries in the Sharpless nebula catalog, a list of more than 300 glowing clouds of gas compiled by American astronomer Stewart Sharpless in the 1950s. Before he published this catalog, Sharpless was a graduate student at Yerkes Observatory in Wisconsin, where he and his colleagues published observational work that helped show that the Milky Way is a spiral galaxy with vast, curved arms.

Spiral galaxies can contain thousands of HII regions, almost all of which are concentrated along their spiral arms. The Seagull Nebula lies in one of the spiral arms of the Milky Way. But this is not the case for all galaxies; while irregular galaxies do contain HII regions, these are jumbled up throughout the galaxy, and elliptical galaxies are different yet again — appearing to lack these regions altogether. The presence of HII regions indicates that active star formation is still in progress in a galaxy.

This image of Sharpless 2-296 was captured by the Wide Field Imager (WFI), a large camera mounted on the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile. It shows only a small section of the nebula, a large cloud that is furiously forming hot stars in its interior. The frame shows Sharpless 2-296 lit up by several particularly bright young stars — there are many other stars scattered across the region, including one so bright that stands out as the gull’s “eye” in pictures of the entire complex.
