The stability of age-zero contact binaries. III
Abstract
The secular and dynamical stability of contact binary models are investigated for various masses Mp, Ms of the primary and secondary components. It is found that, in an Mp - Ms diagram, a stable strip of finite width separates secularly unstable from dynamically unstable regions. The significance of this result for the theory of W UMa stars is discussed.
