Astronomers at the University of Toronto (U of T) have discovered the first pairs of white dwarf and main sequence stars—”dead” remnants and “living” stars—in young star clusters. Described in a new study published in The Astrophysical Journal, this breakthrough offers new insights into an extreme phase of stellar evolution, and one of the biggest mysteries in astrophysics.
