That thinning likely resulted from two stars merging and burning off outer layers during the collision. This rare white dwarf merger left a stripped remnant with a nearly pure hydrogen atmosphere yet ...

A team of U.S. astronomers has observed a binary pair of white dwarfs where one star is actively devouring material from the ...

Hubble has helped uncover a white dwarf that’s likely the result of two stars crashing together. Carbon traces in its atmosphere tell a story of a cosmic merger, a rare phenomenon previously invisible ...
