Life after eruption - I. Spectroscopic observations of 10 nova candidates
Abstract
We have started a project to investigate the connection of post-novae with the population of cataclysmic variables (CVs). Our first steps in this concern improving the sample of known post-novae and their properties. Here we present the recovery and/or confirmation of the old novae MT Cen, V812 Cen, V655 CrA, IL Nor, V2109 Oph, V909 Sgr, V2572 Sgr and V728 Sco. Principal photometric and spectroscopic properties of these systems are discussed. We find that V909 Sgr is a probable magnetic CV, and that V728 Sco is a high-inclination system. We furthermore suggest that the two candidate novae V734 Sco and V1310 Sgr have been misclassified and instead are Mira variables. Based on observations with ESO telescopes, proposal numbers 083.D-0158, 086.D-0428 and 087.D-0323.
