Planetary thermal mass (source code)

= Planetary thermal mass
{title2=$M_{\rm th}=h^3M_\star$}

The scale $M_{\rm th}=h^3M_\star$ makes the Bondi <radius> comparable with the <disk scale height>. It organizes when <planet>-induced disturbances become nonlinear; it is not identical to an exact universal gap-opening <mass>.
