Abstract

The article focuses on the discovery of a 2024 superluminous supernova, SN 2024afav, whose unusual periodic brightness variations provide new evidence supporting the role of magnetars—highly magnetized, rapidly spinning neutron stars—in powering these exceptionally bright stellar explosions. Unlike typical supernovae powered by radioactive decay, superluminous supernovae exceed expected brightness levels, and their light curves often show irregular bumps that have been debated as either interactions with surrounding material or magnetar activity. The observed pattern of brightness "chirps" in SN 2024afav is best explained by a precessing disk of matter around a magnetar, which modulates its energy output over time. While this finding offers a compelling model, some experts note that further examples are needed to confirm magnetars as the definitive energy source behind superluminous supernovae.
