The long-term luminosity evolution of nova shells
Abstract
We present a new analysis of the nova shell luminosities based on Hα and O[III] λ5007 emission lines fluxes, given by Downes & Duerbeck, 2001 (JAD 7, 6) for epochs between one week and several decades after the eruption maximum of classical and recurrent novae. For this purpose, we use new distances from the Gaia Collaboration DR2 (2018) and investigate whether there are significant correlations of shell luminosities to nova speed classes and/or to the different nova light curve types defined by Strope et al 2010 (AJ 140, 34). We describe the differences among these parameters and add some conclusions on the long-term nova shell evolution.
