A White Dwarf Living on the Edge
Astronomers have identified a white dwarf so massive that it might collapse
Astronomers have discovered the smallest and most massive white dwarf ever seen. The smoldering cinder, which formed when two less massive white dwarfs merged, is about 4,300 kilometers across, or somewhat larger than Earth's moon.
These artworks were commissioned by Caltech and Ilaria Caiazzo, the Sherman Fairchild Postdoctoral Scholar Research Associate in Theoretical Astrophysics at Caltech (Pasadena, CA) and lead author of the new study appearing in the July 1 issue of the journal Nature.
