Astronomers at the University of Toronto (U of T) have discovered the first pairs of white dwarf and main sequence stars\u2014\u201d dead\u201d remnants and \u201cliving\u201d stars\u2014in young star clusters. Described in a new study published<\/a> in The Astrophysical Journal<\/i>, this breakthrough offers new insights into an extreme phase of stellar evolution, and one of the biggest mysteries in astrophysics.<\/p>\n

Scientists can now begin to bridge the gap between the earliest and final stages of binary star systems\u2014two stars that orbit a shared center of gravity\u2014to further our understanding of how stars form, how galaxies evolve, and how most elements on the periodic table were created. This discovery could also help explain cosmic events like supernova explosions and gravitational waves, since binaries containing one or more of these compact dead stars are thought to be the origin of such phenomena.<\/p>\n

Most stars exist in binary systems. In fact, nearly half of all stars similar to our sun have at least one companion star. These paired stars usually differ in size, with one star often being more massive than the other. 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
