Spectroscopic confirmation of ASASSN-17mt as a classical nova in the optically thick (Fe curtain) stage
Abstract
ASASSN-17mt (ATel #10772, #10785) has recently been announced as a nova candidate. We obtained a medium resolution spectrum (0.82A/px) using an Alpy600 spectrograph (single exposure, 600 sec, S/N of about 20 in the continuum from 5200-5600A) on 2017 Sept.28.77 UT that confirm this identification and show that the ejecta are optically thick and at moderately high velocity.
