Q and A of the Day: White Dwarfs vs. Neutron Stars?
Q:
What are five differences between white dwarfs and neutron stars?
A:
The major difference is due to the way in which they are formed. 1. White dwarfs are formed from the collapse of low mass stars, less than about 10 time the mass of the Sun. This star loses most of its mass in a wind, leaving behind a core that is less than 1.44 solar mass. On the other hand, neutron stars are formed in the catastrophic collapse of the core of a massive star.

Q&A of the Day
We've decided to introduce a new, intermittent series to the Chandra blog. From time to time, we'll dig into our vast archive of questions submitted by the public and post the answers written by experts at the Chandra X-ray Center. Some of these will be Chandra-specific or at least X-ray astronomy related. Others, well, they'll be somewhat random. Enjoy.
