Schwarzschild criterion

Discovered by Karl Schwarzschild, the Schwarzschild criterion is a criterion in astrophysics where a stellar medium is stable against convection where

${\displaystyle -{\frac {dT}{dZ}}<{\frac {g}{C_{p}}}}$

Where ${\displaystyle g}$ is gravity and ${\displaystyle C_{p}}$ is the heat capacity at constant pressure.
