A study of angular momentum loss in binaries using the free Lagrange method
Using a 3‐dimensional hydrodynamic fluid code based on the Free Lagrange Method, we study the loss of specific angular momentum from a binary system due to an evaporative wind from the companion of a millisecond pulsar. We consider binaries of different mass ratios and winds of different initial velocities and in particular attempt to model the system PSR 1957+20. We are in the process of incorporating the effect of the radiation force from the pulsar and the magnetic field of the companion on the mass outflow. The latter effect would also enable us to study magnetic braking in Cataclysmic Variables and Low Mass X‐ray Binaries.
