- UBC astronomers discover how white dwarf stars get their 'kicks'
12-04-2007 · EurekAlert!
University of British Columbia astronomer Harvey Richer and UBC graduate student Saul Davis have discovered that white dwarf stars are born with a natal kick, explaining why these smoldering embers of sun-like stars are found on the edge rather than at the center of globular star clusters.

- Asymmetric ashes
11-30-2006 · EurekAlert!
Astronomers are reporting remarkable new findings that shed light on a decade-long debate about one kind of supernovae, the explosions that mark a star's final demise: Does the star die in a slow burn or with a fast bang? From their observations, the scientists find that the matter ejected by the explosion shows significant peripheral asymmetry but a nearly spherical interior, most likely implying that the explosion finally propagates at supersonic speed.

- Giant planets do not come as lonely hearts
02-14-2008 · EurekAlert!
Scaled versions of Jupiter and Saturn orbiting a star 5000 light-years away, half as massive as the sun, have been revealed from an effort involving a world-wide net of telescopes, including the UK's Liverpool Telescope on the Canary Islands. This marks the first discovery of another system of planets that has striking similarities with our solar system.

- Astronomers find puzzling dwarf star with complex magnetic fields
12-05-2007 · EurekAlert!
Typically, little M-dwarf stars -- the most common type of star in the galaxy -- are cold, quiet, and dim. Now a team of astronomers led by Edo Berger, a Carnegie-Princeton postdoctoral fellow, found one M-dwarf that doesn't conform. It has an unusually active and complex magnetic field, stronger than our own Sun's, and a huge hot spot that covers half of its surface.

- Planet orbiting a giant red star discovered with hobby-eberly telescope
08-02-2007 · EurekAlert!
A planet orbiting a giant red star has been discovered by an astronomy team led by Penn State's Alex Wolszczan, who in 1992 discovered the first planets ever found outside our solar system. The new discovery is helping astronomers to understand what will happen to the planets in our solar system when our Sun becomes a red-giant star, expanding so much that its surface will reach as far as Earth's orbit.

- Massive black hole smashes record
10-30-2007 · EurekAlert!
Using two NASA satellites, astronomers have discovered the heftiest known black hole to orbit a star. The new black hole, with a mass 24 to 33 times that of our Sun, is more massive than scientists expected for a black hole that formed from a dying star.

- New view of doomed star
06-20-2007 · EurekAlert!
A new composite image of the Eta Carinae from NASA's Chandra X-ray Observatory and Hubble Space Telescope shows the remnants of a massive eruption from the star during the 1840s. Eta Carinae is a mysterious, extremely bright and unstable star located a mere stone's throw -- astronomically speaking -- from Earth at a distance of only about 7500 light years. The star is thought to be consuming its nuclear fuel at an incredible rate, while quickly drawing closer to its ultimate explosive demise.
