The Origins of Blue Stragglers
Blue Stragglers are strange stars that don't seem to fit the standard picture of stellar evolution. A paper published in Nature on the 20th of October by Aaron Geller & Robert Mathieu (see link below) helps shed some light on their origins.
Christopher Tout is the John Kooch-Adams Astronomer at the Institute of Astronomy in Cambridge, and a fellow of Churchill college. He researches stellar evolution, and gives his perspective on the work.
