Entropy-calibrated stellar modeling: Testing and improving the use of prescriptions for entropy of adiabatic convection
L. Manchon, M. Deal, M. -J. Goupil +7
The modeling of convection is a long standing problem in stellar physics. Up-to-now, all ad hoc models rely on a free parameter alpha (among others) which has no real physical just…
