Lagrange Points in a Binary Star System


The Lagrange
points are points of gravitational equilibrium. The L1, L2, and L3
points are locations about which an object, such as a satellite, can be
placed in a quasistable orbit with only small corrections needed. The
equipotential surface passing through the L1 point defines the Roche
lobes of the stars. If either star grows larger than its Roche lobe,
mass transfer from that star to the other will be initiated.
