NOIRLab Press Release:


Stars end their lives in a variety of ways. Low mass stars puff off their outer layers and settle down to become white dwarfs while massive stars end their lives in spectacular supernova explosions. A long hypothesized way for stars to end their lives by collisions of stars or stellar remnants in the densely packed area near a galaxy’s massive black hole. Andrew Levan recently found evidence of this new phenomena while following up a long gamma ray burst. In this podcast, Andrew Levan describes how a variety of telescopes provided the first evidence for this new way for a star to end its life.

Bio: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona

Andrew Levan is a professor at Radbound University in the Netherlands where he  studies astrophysical transients such as Gamma-ray bursts, supernovae, tidal disruption events and most recently the electromagnetic counterparts to gravitational wave sources.
