How Do Wide Binary Stars Form
2012-12-05 13:48:14

Scientists have reported in the journal Nature that they have figured out by using computer simulations how wide binary stars are able to form.

Aging Stars Sculpt Spectacular Shape Of Planetary Nebula
2012-11-08 14:21:55

Astronomers have discovered a pair of stars orbiting each other at the center of a remarkable example of a planetary nebula. The latest find confirms a theory about what controls the spectacular and symmetric appearance of the material flung out into space.

First Planet Discovered In A Quadruple Star System Confirmed
2012-10-31 09:45:16

Justin Crepp, Freimann Assistant Professor of physics at the University of Notre Dame, provided the high-contrast imaging observations that confirmed the first extrasolar planet discovered in a quadruple star system.

Planet Found Orbiting Two Stars
2012-10-15 13:37:20

A team of international astronomers, along with Planethunters.org volunteers, found the first reported case of a planet orbiting twin suns that in turn is orbited by a second distant pair of stars.

Stellar Winds Of Two Massive Stars Tracked Using X-Rays
2012-10-12 16:48:42

Astronomers have X-rayed the stellar winds of two massive stars that are orbiting around one another.

When Massive Stars Collide, Monsters Are Formed
2012-08-07 13:31:56

Astronomers now believe the "monster stars" located in the nearby galaxy the Large Magellanic Cloud (LMC) were formed through the merger of lighter stars.

Searching For Supernova Progenitors
2012-08-04 06:23:15

A progenitor of a type 1a supernova may have been found, according to findings published in the journal Monthly Notices of the Royal Astronomical Society.

New research using data from ESO’s Very Large Telescope has revealed that the hottest and brightest stars, which are known as O stars, are often found in close pairs. Many of such binaries transfer mass from one star to another, a kind of stellar vampirism depicted in this artist’s impression. Credi

The brightest stars in the universe apparently do not like to live alone, according to a new study using ESO's Very Large Telescope (VLT).

Why stop at the dark side of the moon to make music when you can look thousands of light years into space?

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...
