Study Reveals Secrets Of Binary Stars Through Red Explosions
2013-01-25 11:12:34

April Flowers for redOrbit.com - Your Universe Online Astrophysicists have debated the outcome of two binary stars — stars that orbit each other — coming together in a "common envelope" for a long time. A new study from the University of Alberta has finally provided some answers. Theoretical astrophysicist Natalia Ivanova has revealed the workings of a celestial event that produces an explosion so powerful its luminosity approaches that of a supernova. “When this...

Binary Star Orbit Shifts Could Force Planetary Ejections
2013-01-07 03:28:35

redOrbit Staff & Wire Reports - Your Universe Online The orbits of distant binary stars can become altered over time, potentially causing violent disruptions in their planetary systems and possibly causing worlds to become scattered or ejected, an international team of astrophysicists has discovered in a new study. According to the researchers, all planetary systems in which one star is orbited by a second, companion star, can be altered by the gravity of the companion star, but...

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

Lee Rannals for redOrbit.com - Your Universe Online Scientists have reported in the journal Nature that they have figured out by using computer simulations how wide binary stars are able to form. Wide binary stars are two stars that orbit each other at a distance up to a light year. Some binary stars can be very close, while other pairs are extremely far apart. Astronomers have known about wide binary pairs for a long time, but how they form has remained a mystery. Now, astronomers...

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

[ Video 1 ] | [ Video 2 ] | Video 3 ] Lee Rannals for redOrbit.com - Your Universe Online 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. Planetary nebulae are glowing shells of gas around white dwarfs, and Fleming 1 is considered a great example that has strikingly...

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

University of Notre Dame 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. He is a co-author on a paper about the discovery, “Planet Hunters: A Transiting Circumbinary Planet in a Quadruple Star System,” recently posted to the open-access arXiv.org, and submitted for publication to The Astrophysical Journal....

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

Lee Rannals for redOrbit.com - Your Universe Online 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. Researchers said that only six planets are known to orbit two stars, and none of these are orbited by distant stellar companions. "Circumbinary planets are the extremes of planet formation," said Meg Schwamb of Yale University and lead...

Stellar Winds Of Two Massive Stars Tracked Using X-Rays

[Watch the Video: X-ray Satellites Monitor the Clashing Winds of a Colossal Binary] [Watch the Video: Simulation of Colliding Stellar Wind Binary] [Watch the Video: Simulation of Binary Star System] Lee Rannals for redOrbit.com — Your Universe Online Astronomers have X-rayed the stellar winds of two massive stars that are orbiting around one another. Stellar winds can trigger the collapse of surrounding clouds of gas and dust to form new stars, and can also blast the...

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...
