A recent study on pre-supernova neutrinos—tiny cosmic particles that are extremely hard to detect—has brought scientists one step closer to understanding what happens to stars before they explode and die. The study, co-authored by postdoctoral researcher Ryosuke Hirai from the ARC Center of Excellence for Gravitational Wave Discovery (OzGrav) at Monash University investigated stellar evolution models to test uncertain predictions.
