Shock-heated gas in the outbursts of classical novae

Research output: Contribution to journal › Article › peer-review

Abstract

We present a simple model for interactions between the slow and fast phases of mass ejection in classical nova outbursts. A situation develops in which a layer of hot gas sandwiched between two shocks progresses through the slow wind until it 'blows-out', expanding and cooling adiabatically. We calculate the X-ray emission from this model and find that the dynamical timescale is at least as important as the radiative cooling time in determining the form of the X-ray light curves. Models of this type may help to explain the origin of X-ray emission in some classical nova outbursts. © 1994 Kluwer Academic Publishers.
