Astronomers Link Superluminous Supernovae to Magnetar Formation
Recent observations of supernova SN 2024afav provide evidence that superluminous supernovae are powered by newly formed magnetars, confirming longstanding theoretical predictions.
Astronomers have observed a superluminous supernova, SN 2024afav, exhibiting unique brightness oscillations, providing evidence that such extraordinary explosions are powered by newly formed magnetars—highly magnetized, rapidly spinning neutron stars. This discovery confirms a theory proposed 16 years ago by a UC Berkeley physicist, linking magnetar formation to the immense luminosity of these supernovae. The findings, published in Nature, mark the first observational evidence of this phenomenon, offering new insights into the mechanisms driving some of the universe's brightest stellar explosions.
