From Common Envelope to Pre-Cataclysmic Variables: An Observational Test of Common Envelope Evolution
The generally accepted evolutionary scenario for cataclysmic variables (CVs) is common envelope (CE) evolution (Iben &Livio 1993) proposed by Paczyński (1976). The secondary spirals towards the giant’s compact core converting orbital energy into kinetic energy of the giant's envelope and the envelope is ejected. The dynamics of the red dwarf and red giant envelope interaction have been studied by several groups (Livio & Soker 1988; Taam & Bodenheimer 1991). After the ejection of the red giant envelope the post common envelope detached binaries (PCEBs) are formed.
