 Common-envelope energy formalism (source code)

= Common-envelope energy formalism

The <common-envelope energy formalism> equates a fraction $\alpha_{\rm CE}$ of the released orbital <energy> to the envelope binding <energy>, often written $E_{\rm bind}=GM_dM_{\rm env}/(\lambda R_d)$. It estimates the post-envelope separation but compresses uncertain hydrodynamics into $\alpha_{\rm CE}$ and $\lambda$.
