Detailed Description

periastron option Circularisation at periastron: anew=a_old(1-e_old)

After the circularisation the binary angular momentum decreases of a factor (Jnew-Jold)/Jold = 1/sqrt(1+e) -1, it ranges from 5% for small eccentriciteis (e=0.01) to ~29% for e->1

◆ check_activation()

bool StandardCircularisation::check_activation ( Binstar * binstar ) const

protectedvirtualinherited

Check the triggering condition of the circularisation

Parameters

Returns: True if the RLO is ongoing

Reimplemented in CircularisationPeriastronFull.

◆ circularise()

int CircularisationPeriastron::circularise ( _UNUSED Binstar * binstar )

overrideprotectedvirtual

Circularisation Periastron.

Circularisation at periastron: anew=a_old(1-e_old)

Parameters

binstar pointer to the binary

Returns: EXIT_SUCCESS

Implements StandardCircularisation.

◆ estimate_accreted_mass()

virtual double Process::estimate_accreted_mass	(	_UNUSED double	DM,
		_UNUSED Star *	donor,
		_UNUSED Star *	accretor,
		_UNUSED Binstar *	binstar
	)		const

inlinevirtualinherited

Public interface to allow the user to get information without actually evolving the systems. NOTICE: to be self-consistent the protected and private methods (such DA and DE should use these methods) when changing the properties of stars and binaries. This function should be an interface for the user to return the amount of mass accreted on the accretor given the binary, the donor and the available amount of mass DM. NOTICE: internally the accrete mass should use this method to be self-consistent

Parameters

DM	amount of mass available to be accreted in Msun.
donor	Pointer to the Star that is donating the mass
accretor	Pointer to the star that is receiving the mass
binstar	Pointer to the binary system hosting the donor and the accretore

Returns: the amount of accreted mass

Reimplemented in WindaccretionHurley.
