The Long-Term Spectroscopic Misadventures of AG Dra with a Nod Toward V407 Cyg: Degenerates Behaving Badly

Abstract

We present some results of an ongoing study of the long-term spectroscopic variations of AG Dra, a prototypical eruptive symbiotic system. We discuss the effects of the environment and orbital modulation in this system and some of the physical processes revealed by a comparison with the nova outburst of the symbiotic-like recurrent nova V407 Cyg 2010.
