Classes#

`star_params`	star_params is an object to store stellar parameters. These parameters can be interpolated from an isochrone, from a black body function, or constructed from scratch.
`stellar_params_obj`	Base stellar parameters object. Provides common functionality across objects used for obtaining star parameters.

API#

class phitter.params.star_params.star_params(mass_init=0.0 * u.solMass, mass=0.0 * u.solMass, rad=0.0 * u.solRad, lum=0.0 * u.solLum, teff=0.0 * u.K, logg=0.0, syncpar=1.0)#

Bases: object

star_params is an object to store stellar parameters. These parameters can be interpolated from an isochrone, from a black body function, or constructed from scratch.

mass_initAstropy Quantity, unit:solMass: Initial stellar mass in solar masses
massAstropy Quantity, unit:solMass: Current stellar mass in solar masses
radAstropy Quantity, unit:solRad: Current stellar radius in solar radii
lumAstropy Quantity, unit:solLum: Current stellar luminosity in solar luminosities
teffAstropy Quantity, unit:K: Current effective temperature of star in Kelvin
loggfloat: Current surface gravity of star, specified as a unitless quantity as log_10 (g / [1 * cm s^-2])
syncparfloat: The ratio between the (sidereal) orbital and rotational period (wrt the sky).
filtslist_like: List of phitter filters / passbands that mags and pblums are generated for.
magsarray_like(dtype=float): Array of apparent magnitude in filters / passbands being used.
mags_absarray_like(dtype=float): Array of absolute magnitude in filters / passbands being used.
pblumsarray_like(dtype=Astropy Quantity): Array of passband luminosities in filters / passbands being used, each in units of solar luminosities. Passband luminosity in a filter / passband is defined as the luminosity of the star only in that passband.
