Spectroscopic and photometric confirmation of ASASSN-21br as an AM CVn system
Abstract
We report on spectroscopic and photometric follow up of ASASSN-21br, a candidate AM CVn (ATel #14405), which was discovered by the All-Sky Automated Survey for SNe (ASAS-SN, Shappee et al. 2014, ApJ, 788, 48) on 2021-02-13.12 UT. After a very rapid outburst lasting for less than 3 days, followed by a sudden dip, the system re-brightened and is still in outburst as of 2021-02-23.07 (see latest ASAS-SN light curve below).
