SNAD catalogue of M-dwarf flares from the Zwicky Transient Facility

A. S. Voloshina, A. D. Lavrukhina, M. V. Pruzhinskaya +11

Most of the stars in the Universe are M spectral class dwarfs, which are known to be the source of bright and frequent stellar flares. In this paper, we propose new approaches to d…
