Bases: object

Class to compute the observables for a modeled binary system, given stellar parameters and binary parameters.

Parameters:

bin_observablesobservables

observables object, with obs_times, obs_filts, and obs_types specified.

use_blackbody_atmbool, default=False

Use blackbody atmosphere instead of default Castelli & Kurucz atmosphere. Default: False (i.e.: using a C&K atm by default)

use_compact_objectbool, default=False

If true, sets eclipse_method to ‘only_horizon’ in PHOEBE, which is necessary for compact companions without eclipses. Default: False

print_diagnosticsbool, default=False

Print diagnostic messages, helpful for debugging.

par_computebool, default=False

Uses parallelization when computing with PHOEBE.

num_par_processesint, default=8

Number of processes to use when parallel computing with PHOEBE.

compute_obs(star1_params, star2_params, binary_params, irrad_frac_refl=1.0, num_triangles=1500, make_mesh_plots=False, mesh_plot_phases=np.array([0.25]), animate=False, mesh_plot_fig=None, mesh_plot_subplot_grid=None, mesh_plot_subplot_grid_indexes=None, mesh_temp=False, mesh_temp_cmap=None, plot_name=None, mesh_plot_kwargs={})

Function to compute observables with the specified star and binary system parameters.

Parameters:

star1_paramsstar_params

star_params object, with parameters for the primary star.

star2_paramsstar_params

star_params object, with parameters for the secondary star.

binary_paramsbinary_params

binary_params object, with parameters for the binary system configuration.

irrad_frac_reflfloat, default=1.0

Fraction reflectivity for irradiation

num_trianglesint, default=1500

Number of triangles to use for PHOEBE’s mesh model of each stellar atmosphere. For contact system, num_triangles*2 are used for contact envelope.

make_mesh_plotsbool, default=False

Make a mesh plot of the binary system. Default: False

plot_namestr, default=None

Name for the output plots, if making a mesh plot

Returns:

observables

observables object returned. Deep copy of input observables object, with obs also defined, with modeled values.

model_obs_calc.phased_obs(observation_times, binary_period, t0, filts_list=[kp_filt, h_filt])

Phase observation times to a given binary period and t0
