Detailed Description

2-fluids equation of state base class.

Fluid 1 is supposed to correspond to neutrons, whereas fluid 2 corresponds to e.g. protons. Neutron 4-velocity is $u^\alpha_{\rm n}$ and proton one is $u^\alpha_{\rm p}$

Therefore, the EOS is defined by giving two log-enthalpies AND a relative velocity as inputs. The output are then: two baryonic densities, the total energy density and pressure The enthalpies $f_1$ and $f_2$ are obtained through the formula

${\rm d}{\cal E}=f^1{\rm d}n_1+f^2{\rm d}n_2+\alpha{\rm d}\Delta^2 \label{eeosbfdefent}$

see Comer, Novak & Prix. Log-enthalpies are then defined as $H_1 = \ln\left( \frac{f^1}{m_1c^2} \right)$ , where $m_1$ is the mass of a particle of the first fluid. (same for $H_2$ ) The relative velocity $\Delta^2$ is defined as in Comer, Novak & Prix. It can be seen as the neutron velocity seen in the frame of protons (or vice-versa): $\Gamma_\Delta = -g_{\alpha\beta} u^\alpha_{\rm n} u^\beta_{\rm p}$ ()

◆ press_ent()

Cmp Lorene::Eos_bifluid::press_ent	(	const Cmp &	ent1,
		const Cmp &	ent2,
		const Cmp &	delta2,
		int	nzet,
		int	l_min = `0`
	)		const

Computes the pressure from the log-enthalpy fields and the relative velocity.

Parameters

ent1	[input, unit: ] log-enthalpy
ent2	[input, unit: ] log-enthalpy
delta2	[input, unit: ] relative velocity $\Delta^2$
nzet	number of domains where the pressure is to be computed.
l_min	index of the innermost domain is which the pressure is to be computed [default value: 0]; the pressure is computed only in domains whose indices are in [l_min,l_min+nzet-1] . In the other domains, it is set to zero.

Returns: pressure field [unit: $\rho_{\rm nuc} c^2$ ], where $\rho_{\rm nuc} := 1.66\ 10^{17} \ {\rm kg/m}^3$

◆ press_nbar_p()

virtual double Lorene::Eos_bifluid::press_nbar_p	(	const double	nbar1,
		const double	nbar2,
		const double	delta2
	)		const

pure virtual

Computes the pressure from the baryonic densities and the relative velocity.

(virtual function implemented in the derived classes).

Parameters

nbar1	[input] baryonic density of the first fluid
nbar2	[input] baryonic density of the second fluid [unit: $n_{\rm nuc} := 0.1 \ {\rm fm}^{-3}$ ]
delta2	[input, unit: ] relative velocity $\Delta^2$

Returns: pressure p [unit: $\rho_{\rm nuc} c^2$ ], where $\rho_{\rm nuc} := 1.66\ 10^{17} \ {\rm kg/m}^3$

Implemented in Lorene::Eos_bf_tabul, Lorene::Eos_bf_poly_newt, and Lorene::Eos_bf_poly.

◆ sauve()

virtual

Save in a file.

Reimplemented in Lorene::Eos_bf_tabul, Lorene::Eos_bf_poly_newt, and Lorene::Eos_bf_poly.

◆ trans2Eos()

virtual Eos* Lorene::Eos_bifluid::trans2Eos ( ) const

pure virtual

Makes a translation from Eos_bifluid to Eos .

(virtual function implemented in the derived classes).

This is only useful for the construction of a Et_rot_bifluid star and ought not to be used in other situations.

Parameters

relat [input] Relativistic EOS or not.

Implemented in Lorene::Eos_bf_tabul, Lorene::Eos_bf_poly_newt, and Lorene::Eos_bf_poly.
