The superluminous Type Ia supernova SN 2022erq was powered by ejecta crashing into a ~3-solar-mass circumstellar shell, implying the progenitor's mass-loss rate escalated from ~0.04 to ~0.6 solar masses per year in its final decades.

SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss
The superluminous Type Ia supernova SN 2022erq was powered by ejecta crashing into a ~3-solar-mass circumstellar shell, implying the progenitor's mass-loss rate escalated from ~0.04 to ~0.6 solar masses per year in its final decades.
