class EclipsingBinaryStar(**kwargs)[source]

Bases: PeriodicVariableStar

A toy model for a detached eclipsing binary star.

It is assumed that the stars are spherical, SED is black-body, and the orbits are circular. t0 is the epoch of the primary minimum. No limb darkening, reflection, or other effects are included.

Parameterized values include:

dec - The object’s declination in degrees. [from BasePhysicalModel]
distance - The object’s luminosity distance in pc. [from BasePhysicalModel]
inclination - The inclination of the orbit, in degrees.
major_semiaxis - The major semiaxis of the orbit, in AU.
period - The period of the source, in days. [from PeriodicModel]
primary_radius - The radius of the primary star, in solar radii.
primary_temperature - The effective temperature of the primary star, in kelvins.
ra - The object’s right ascension in degrees. [from BasePhysicalModel]
redshift - The object’s redshift. [from BasePhysicalModel]
secondary_radius - The radius of the secondary star, in solar radii.
secondary_temperature - The effective temperature of the secondary star, in kelvins.
t0 - The t0 of the zero phase, date. [from PeriodicModel]
