The Hunt for Old Novae

Tappert C.; Vogt N.; Schmidtobreick L.; Ederoclite A.

Abstract

We inform on the progress of our on-going project to identify and classify old classical novae, using deep UBVR photometry and subsequent spectroscopy for a proper candidate confirmation, and time-resolved observations in order to find the orbital period and other physical properties of the identified old novae. This way, we have already increased the number of confirmed southern and equatorial post-novae from 33 to 50, and determined new orbital periods of eight objects. As an example, we sumarize the results on V728 Sco (Nova Sco 1862) which we found to be an eclipsing system with a 3.32 h orbital period, displaying high and low states similar to dwarf nova outbursts. Analysis of the low-state eclipse indicates the presence of a small hot inner disk around the white dwarf component.
