J1010+2358 PISN’t a direct descendant of the first stars
We thought we finally found a direct descendant of the first stars. A follow-up observation showed that it PISN’t.

All stars die, but not all stars die the same. Some will explode and leave no trace behind. These special explosions with no trace are called pair-instability supernovae (PISNe) and only happen in the most massive of stars. Today’s paper from 2009 investigates a unique supernova, SN 2007bi, that was initially thought to be the first PISN ever observed.
How do the most massive stars explode? A new model of massive stars predicts new observational evidence.
Scientists search for signatures of pair-instability supernovae in thousands of Sloan Digital Sky Survey Stars.
