Roche-lobe

WebDec 24, 2024 · The Roche lobe is a gravitational potential well of a two-body configuration. Technically, it is the potential energy per unit test mass which is orbiting the center-of-mass of a binary-star system at the same rate as the two stars. It is often depicted with equipotential surfaces and the 5 Lagrange points. WebIf the inspiralling star fills its Roche lobe outside the innermost stable circular orbit of the hole, gas will flow through the inner Lagrange point (L1) to the hole. We give a new, accurate interpolation formula of the volume enclosed by the relativistic Roche lobe. If this mass transfer happens on a time-scale faster than the thermal time ...
