On the nature of the soft X-ray emission from Nova GQ Muscae 1983

A model is proposed for the interpretation of the extended phase of soft X-ray emission observed for Nova GQ Muscae 1983. It is argued that such a phase is a forced consequence of the evolution of classical novae in outburst (MacDonald, Fujimoto, & Truran 1985). The early appearance of the soft X-ray emission (Ögelman, Krautter, & Beuermann 1987) is interpreted to be a consequence of common envelope (CE) driven mass loss, occurring over the first few hundred days of the nova outburst. The subsequent turn-off of GQ Muscae as a soft X-ray source occurred between early 1992 and late 1993. The approximately 10 year phase of soft X-ray emission thus defined is found to be consistent with the nuclear burning timescale for the exhaustion of the residual (post common envelope phase) hydrogen envelope on a 1 M ⊙ white dwarf, in a binary system of period 85.5 s (Diaz & Steiner 1989).
