class blackbody_params.bb_stellar_params(*args, **kwargs)

Bases: phitter.params.star_params.stellar_params_obj

stellar_params class, to derive stellar parameters from a blackbody atmosphere

Parameters:

ext_Ksfloat, default=2.63

Extinction of stellar parameters object in Ks band.

distAstropy Quantity, length units, default=7.971e3*u.pc

Distance to object, specified during isochrone creation.

filts_list[filter], default=[filters.nirc2_kp_filt(), filters.nirc2_h_filt()]

List of filters to compute synthetic photometry.

ext_lawstr, default=’NL18’

Choice of extinction law to use when computing synthetic photometry. Default is ‘NL18’, corresponding to Nogueras-Lara+ 2018.

calc_star_params(mass, rad, teff)

Calculate stellar parameters from a blackbody, returned as a star_params object

Parameters:

massAstropy Quantity, unit:solMass

Stellar mass in solar masses

radAstropy Quantity, unit:solRad

Stellar radius in solar radii

teffAstropy Quantity, unit:K

Stellar effective temperature in Kelvin

Returns:

star_params

star_params object returned, with stellar parameters based on a blackbody atmosphere and input stellar parameters.
