InitialBinaryTable

class cosmic.sample.initialbinarytable.InitialBinaryTable

Bases: object

classmethod InitialBinaries(m1, m2, porb, ecc, tphysf, kstar1, kstar2, metallicity, **kwargs)

Create single binary

Parameters

m1 : float

Primary mass [Msun]

m2 : float

Secondary mass [Msun]

porb : float

Orbital period [days]

ecc : float

Eccentricity

tphysf : float

Time to evolve the binary [Myr]

kstar1 : array

0-14 Initial stellar type of the larger object; main sequence stars are 0 if m < 0.7 Msun and 1 otherwise

kstar2 : array

0-14 Initial stellar type of the smaller object; main sequence stars are 0 if m < 0.7 Msun and 1 otherwise

metallicity : float

Metallicity of the binaries; Z_sun = 0.02

**kwargs

binfracfloat

System-specific probability of the primary star being in a binary

Returns

InitialBinaries : DataFrame

Single binary initial conditions

classmethod sampler(format_, *args, **kwargs)

Fetch a method to generate an initial binary sample

Parameters

format : str

the method name; Choose from ‘independent’ or ‘multidim’

*args

the arguments necessary for the registered sample method; see help(InitialBinaryTable.sampler(‘independent’) to see the arguments necessary for the independent sample
