Episodic modulations in supernova radio light curves from luminous blue variable supernova progenitor models

by T. Moriya, J. Groh, and G. Meynet, A&A 556, L2

Core collapse supernova of type IIb are often interpreted as the outcome of binary evolution. Episodic variations in the radio light curves point to mass loss variations of the precursor, which are usually explained with binary scenarios. The authors use predictions from their latest stellar evolution models to show that single stars can produce radio light curves that are consistent with the observations, too.
