Webcalled Roche-lobe overflow (RLOF). The effective Roche-lobe radiusRL only depends on the orbital separation A and the mass-ratioq. For star ‘1’ with mass M1, it is well … The precise shape of the Roche lobe depends on the mass ratio q=M1/M2{\displaystyle q=M_{1}/M_{2}}, and must be evaluated numerically. However, for many purposes it is useful to approximate the Roche lobe as a sphere of the same volume. An approximate formula for the radius of this … See more In astronomy, the Roche lobe is the region around a star in a binary system within which orbiting material is gravitationally bound to that star. It is an approximately teardrop-shaped region bounded by a critical See more In a binary system with a circular orbit, it is often useful to describe the system in a coordinate system that rotates along with the objects. In this non-inertial frame, one must consider See more When a star "exceeds its Roche lobe", its surface extends out beyond its Roche lobe and the material which lies outside the Roche lobe can "fall off" into the other object's Roche lobe via the first Lagrangian point.
