Spectroscopic classification of PNV J00424144+4117377 and PNV J00414889+4109148 as nova eruptions in M31
Abstract
We obtained a spectrum of classical nova candidate PNV J00424144+4117377 (see ATel #11784) with the SPRAT spectrograph (resolution R 350; Piascik et al. 2014) on the 2-m Liverpool Telescope (Steele et al. 2004) on 2018 July 02.14 UT. A spectrum of PNV J00414889+4109148 (see CBAT TOCP and ATel #11807) was taken on 2018 July 07.18 UT. Both spectra show strong Balmer emission lines (H & alpha; to H & delta;) and both also show the three emission lines from multiplet 42 of Fe II. The FWHM of the H & alpha; emission line is 1200 km/s for PNV J00424144+4117377 and 1500 km/s for PNV J00414889+4109148.
