White Dwarf GD 362
(Preview)
Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust. The discovery might provide insights into our own solar system’s eventual demise several billion years from now.
Solar systems may continue to exis...

Alpha Geminorum
(Preview)
Castor ( Gem / Geminorum / Alpha Geminorum) is the second brightest star in the constellation Gemini and one of the brightest stars in the nighttime sky. Although it has the Bayer designation "alpha", it is actually fainter than Beta Geminorum (Pollux). [url=http://en.wikipedia.org...

Second generation planets
(Preview)
Title: Second generation planets Authors: Hagai B. Perets Planets are typically thought to form in protoplanetary disks left over from protostellar disk of their newly formed host star. However, an additional planetary formation route may exist in old evolved binary systems. In such systems st...

HD156668b
(Preview)
Second smallest exoplanet found to date discovered at Keck Planet hunters using Keck Observatory have detected an extrasolar planet that is only four times the mass of Earth. The planet is the second smallest exoplanet ever discovered and adds to astronomers' growing cadre of low mass planets cal...

HD131488
(Preview)
Using the Gemini South telescope in Chile, astronomers at UCLA have found dusty evidence for the formation of young, rocky planets around a star some 500 light years distant. But these potential extrasolar worlds are alien in an even more intriguing way In the aftermath of collisions between plane...

Y-155
(Preview)
University of Notre Dame astronomer Peter Garnavich and a team of collaborators have discovered a distant star that exploded when its center became so hot that matter and anti-matter particle pairs were created. The star, dubbed Y-155, began its life around 200 times the mass of the sun but probabl...

IK Pegasi
(Preview)
IK Pegasi (or HR 8210) is a binary star system in the constellation Pegasus. At a distance of about 150 light years from the Solar System, it is just luminous enough to be seen with the unaided eye. The primary (IK Pegasi A) is a main sequence, A-class star that displays minor pulsations in luminosity. I...
