On various criticisms of the contact discontinuity model
Abstract
We discuss various criticisms raised recently by Lucy and Wilson, by Papaloizou and Pringle, and by Smith, Robertson, and Smith against the contact discontinuity model for contact binaries. In the process we discover a promising means by which the filled fraction occupied by the common envelope could, in principle, be determined mechanistically for a contact binary of given total mass, angular momentum, initial chemical composition, and age.
