Observations of an ultra-bright supernova suggest a wobbling magnetar engine, caused by Lense–Thirring precession, could explain why some supernovae are 10–100 times brighter than expected.
High-cadence observations of the SLSN-I SN 2024afav reveal chirped light-curve bumps linked to a magnetar central engine with an infalling disk undergoing Lense–Thirring precession. Modeling constrains the magnetar’s spin to about 4.2 ms and its magnetic field to ~1.6×10^14 G, providing the first observational evidence of LT frame-dragging in a magnetar’s environment and supporting magnetar spin-down as the source of extreme luminosity in SLSNe-I.
