Many stars are born in binary systems so an expanding red giant star
will sometimes collide with an orbiting companion star.

At issue, explained lead study author and doctoral student Ben Shappee, is the identity of the white dwarf's companion - is it another white dwarf, or a giant star
, or even a star like our sun?
