Etymology
Named after Édouard Roche.
Meanings
-
The teardrop-shaped region around a star in a binary system within which orbiting material is gravitationally bound to that star.
Generally, mass transfer by Roche lobe overflow is required to power LMXRB's, since low mass stars never exhibit strong stellar winds.
2012, C. de Loore, C. Doom, Structure and Evolution of Single and Binary Stars, page 386:A further interesting situation (although not one of much relevance for this book) comes about if both stars for some reason fill their Roche lobes simultaneously.
2002, Juhan Frank, Andrew King, Derek Raine, Accretion Power in Astrophysics, page 54:If only one component accurately fills its Roche lobe the system is semi-detached. If neither fills its Roche lobe, it is detached.
