A Star's Death by a Thousand Cuts: The Runaway Periodic Eruptions of AT2023uqm
AT2023uqm is a nuclear transient showing at least five periodic optical flares, making it the second confirmed case of periodicity after ASASSN-14ko. Uniquely, these flares show a nearly exponential increase in energy—a 'runaway' phenomenon indicating the star's progressive destruction. This suggests AT2023uqm is likely an rpTDE involving low-mass stars.
