Photometric data gathered by INTEGRAL's Optical Monitoring Camera (OMC) has been used to study selected eclipsing binary stars for which the light curve had hitherto not been analyzed.

Theorists have long wondered how massive stars--up to 120 times the mass of the Sun--can form without blowing away the clouds of gas and dust that feed their growth.

Even some stars go ballistic, racing through interstellar space like bullets and tearing through clouds of gas.

In a paper published in the December 2008 issue of Astronomy and Astrophysics, astronomer Joel Kastner and his team suggest that planets may easily form around certain types of twin (or “binary”) star systems.

The explosion of a binary star inside a planetary nebula has been captured by a team led by UCL (University College London) researchers – an event that has not been witnessed for more than 100 years.

A new image released by ESO shows the amazing intricacies of a vast stellar nursery, which goes by the name of Gum 29. In the center, a small cluster of stars — called Westerlund 2 — has been found to be the home of one of the most massive double star systems known to astronomers.

Enormous masses of dust floating around a binary star system suggest that two Earth-like planets demolished each other in a violent collision.

ESA’s orbiting gamma-ray observatory, Integral has revealed a new population of exotic and dusty binary stars which might represent a brief evolutionary period in a binary star’s life. The findings bring to light a gap in our knowledge of the formation and evolution of such binary star systems.

A team of stellar astronomers is engaged in an interstellar CSI (crime scene investigation). They have two suspects, traces of assault and battery, but no corpse.

Lyra Constellation -- Lyra (the lyre) is a prominent, although fairly small, northern constellation. It was one of Ptolemy's 48 constellations, and also counts among the modern 88 constellations. Its brightest star is Vega (Alpha Lyrae), which together with Altair (Alpha Aquilae) and Deneb (Alpha Cygni) forms the large asterism known as the Summer Triangle. Beta Lyr is a half separated (i.e. one of the stars reached its Rochevolume) eclipsing binary of a cream-white colour. The...

X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...

X-ray Binaries -- X-ray binaries are a class of binary stars that are very luminous in X-rays. The X-rays are produced by matter falling from one component (usually a relatively normal star) to the other component, which is a neutron star or a black hole. The infalling matter releases gravitational potential energy, up to several tens of per cent of its rest mass as X-rays. (Hydrogen fusion releases about 0.7 per cent of rest mass) X-ray binaries are further subdivided into...

Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...

Triple Star -- A triple star system consists of three gravitationally bound stars. The stars are in orbits around a common center of mass, usually so that two of the stars form a close binary star and the third is further away. This configuration is often called a hierarchical triple star. Multiple stars containing more than three stars can usually be decomposed to binaries and single stars that are in a hierachically bound system. ----- Click here to learn more on this...
