.. module:: xpsi.Star .. _star: Star ==== Instances of :class:`~.Star.Star` are objects representing a model star. A model star is constituted by: * an ambient Schwarzschild spacetime solution; * a discrete representation (on leaves of a spacetime foliation) of an embedded stellar 2-surface exterior to which the ambient spacetime solution is assumed valid; * a discrete representation of the local comoving source radiation field in time and photon phase-space over the stellar 2-surface; * a discrete representation of the time-invariant null mapping from the stellar 2-surface to effective infinity; * and low-level integrators of the radiation field incident in the neighbourhood of a point at effective infinity to obtain pulses. .. autoclass:: xpsi.Star.Star :members: photospheres, update :show-inheritance:
