◆ temp_Hs_p()

double Lorene::Ideal_gas::temp_Hs_p	(	double	ent,
		double	sb
	)		const

virtual

Computes the temperature from the log-enthalpy and entropy per baryon (virtual function implemented in the derived classes).

Parameters

ent	[input, unit: ] log-enthalpy H defined by $H = c^2 \ln\left( {e+p \over m_B c^2 n} (to be modified) \right)$ , where e is the (total) energy density, p the pressure, n the baryon density, and the baryon mass
sb	[input, unit: ] entropy per baryon

Returns: temperature [unit: MeV]

Implements Lorene::Hot_eos.
