The study, published Monday in the journal Nature Astronomy, suggests that white dwarf stars are the main source of carbon atoms in the Milky Way, a chemical element known to be crucial to all life.
In fact, 90 percent of all stars in the universe end up as white dwarf stars.
The scientists behind the new study used observations of white dwarfs in open star clusters, groups of a few thousand stars formed around the same time, in the Milky Way by the WM
They measured the stars' initial-final mass relation, which is the relationship between the stars' masses when they first formed and their masses as white dwarfs.
However, the study found that the stars' masses as white dwarfs were larger than the scientists had anticipated considering their initial mass when they first formed.
