redback.photosphere.TDEPhotosphere

class redback.photosphere.TDEPhotosphere(time: ndarray, luminosity: ndarray, mass_bh: float, mass_star: float, star_radius: float, tpeak: float, beta: float, rph_0: float, lphoto: float, **kwargs: None)[source]

Bases: object

__init__(time: ndarray, luminosity: ndarray, mass_bh: float, mass_star: float, star_radius: float, tpeak: float, beta: float, rph_0: float, lphoto: float, **kwargs: None) → None[source]

Photosphere that expands/recedes as a power law of Mdot

Parameters:

time – time in source frame in days
luminosity – luminosity
mass_bh – black hole mass in solar masses
mass_star – star mass in solar masses
star_radius – star radius in solar radii
tpeak – peak time in days
beta – dmdt power law slope
rph_0 – initial photosphere radius
lphoto – initial photosphere luminosity

__call__(**kwargs): Call self as a function.
