Astrophysicists have identified magnetars as the likely power source behind superluminous supernovae, the universe's brightest explosions. New research shows these rapidly spinning neutron stars warp spacetime and transfer rotational energy to stellar debris, though observed light curve irregularities challenge standard models. The findings help explain the extreme brightness but reveal complexities in how magnetar energy interacts with surrounding material.
Background
Superluminous supernovae are exceptionally bright stellar explosions that have puzzled astronomers for years. Magnetars, neutron stars with extremely powerful magnetic fields, have been a leading theoretical explanation for their energy source.
