Physical Review D Study Ties 2 Supernova Puzzles to Flavor-Changing Neutrinos

Summary
A new Physical Review D paper argues neutrinos that switch flavor could help explain why observed core-collapse supernova outcomes diverge from long-standing models.
Current simulations rely on neutrinos to drive the blast but largely omit their identity-changing behavior, leaving a possible gap in how collapses become neutron stars, black holes, or visible explosions.
One mismatch is numerical: star-formation rates imply more supernovae than astronomers actually detect, and identified progenitors include too few red supergiants.
The idea could also bear on black-hole remnants, where gravitational-wave merger data point to a mass gap that existing collapse theory still struggles to reproduce.
