UCSB astrophysicists make discovery about recent supernova explosion

An international team of scientists, including astrophysicists from UC Santa Barbara, has discovered that a supernova that exploded in August –– dubbed the supernova of a generation –– was a "white dwarf" star, and that its companion star could not have been a "red giant," as previously suspected. The findings are published in two papers in the journal Nature this week.

Contributors included scientists from UCSB and affiilated Las Cumbres Observatory Global Telescope Network: Lars Bildsten, Andy Howell, BJ Fulton, Federica Bianco, Benjamin Dilday, Melissa Graham, and David Sand and Jerod Parrent.
