Attributes¶
- class isoc_interp_params.isoc_mist_stellar_params(age=4000000.0, met=0.0, use_atm_func='merged', phase=None, *args, **kwargs)[source]¶
Bases:
phitter.params.star_params.stellar_params_obj
stellar_params class, to derive stellar parameters from a MIST isochrone.
- Parameters:
- agefloat, default=4e6
Age of the isochrone, specified in years. Default: 4e6 (4 Myr old).
- metfloat, default=0.0
- ext_Ksfloat, default=2.63
Extinction of stellar parameters object in Ks band. Used for calculating synthetic photometry.
- distAstropy Quantity, length units, default=7.971e3*u.pc
Distance to the isochrone, used for calculating synthetic photometry.
- 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.
- use_atm_funcstr, default=’merged’
Atmospheric function to use for calculating synthetic photometry. Options are ‘merged’ for merged atmospheres from SPISEA, ‘castelli’ for Castelli & Kurucz (2004) atmospheres, or ‘phoenix’ for Phoenix v16 (Husser et al., 2013) atmospheres.
- phasestr, default=None
If specified, only select stars from a specific stellar evolution phase. Options are ‘PMS’, ‘MS’, ‘RGB’, ‘CHeB’, ‘EAGB’, ‘TPAGB’, ‘postAGB’, or ‘WR’. If phase is None, then all stellar evolution phases are included. Default: None (all stellar evolution phases).
- interp_star_params_mass_init(mass_init)[source]¶
Interpolate stellar parameters from the isochrone, given an initial mass for the star.
- Parameters:
- mass_initfloat
Initial stellar mass as float, in units of solar masses.
- Returns:
- star_params
star_params object returned, with stellar parameters interpolated from the MIST isochrone.
- interp_star_params_rad(rad)[source]¶
Interpolate stellar parameters from the isochrone, given a radius for the star.
- Parameters:
- radfloat
Stellar radius as float, in units of solar radii.
- Returns:
- star_params
star_params object returned, with stellar parameters interpolated from the MIST isochrone.
