Hubble finds Mass of White Dwarf

Posted by CowboyNeal on from the gully-dwarf-mass-still-unknown dept.

Chris Bradshaw writes "The mass of the nearest white dwarf star to Earth has been measured accurately for the first time. from the article: 'Sirius B is just 12,000 km (7,500 miles) in diameter, similar to Earth, but its mass is 98% that of the Sun. Studying Sirius B has been difficult because of the bright light coming from its neighbour Sirius A, the "Dog Star." The results, published in the Monthly Notices of the Royal Astronomical Society, come from astronomers using the Hubble Space Telescope.'"
