From Science Daily

Since its launch in 1999, it has explored galactic cores, studied stellar evolution, investigated regions around black holes, and observed bursts of intense radiation from distant stars and galaxies.

From Science Daily

Though one might be tempted to assume that these stars evolve at the same rate, more massive stars tend to live shorter lives and go through the stages of stellar evolution much faster than their lower mass companions.

From Science Daily

Finding these post-common envelope systems that contain both a "dead" stellar remnant and "living" star -- otherwise known as white dwarf-main sequence binaries -- provides a unique way to investigate this extreme phase of stellar evolution.

From Science Daily

"Binary stars play a huge role in our universe," says lead author Steffani Grondin, a graduate student in the David A. Dunlap Department for Astronomy & Astrophysics at U of T. "This observational sample marks a key first step in allowing us to trace the full life cycles of binaries and will hopefully allow us to constrain the most mysterious phase of stellar evolution."
