flag Astronomers observe a massive star's final "hiccuping" stages, confirming theories on how huge stars explode.

flag Astronomers, including a team from Queen's University Belfast, have observed a rare "hiccuping" star, 150 times the mass of the sun, in its final stages before explosion. flag The star underwent extreme pulses due to a process called Pulsational Pair Instability (PPI), where its hot core rapidly contracts and expands. flag This confirmed theoretical predictions and provides insights into how massive stars function and shape the universe. flag The findings were published in the Astrophysical Journal.
