ziji

ziji simulates the X-ray spectra of black hole X-ray binaries, incorporating the effects of returning radiation. It uses a disk+corona model, considering both thermal disk and reflection components. The model assumes a lamppost corona in Kerr spacetime and improves upon previous calculations by self-consistently determining the ionization parameter at each radial coordinate of the disk, resulting in more realistic reflection spectra.

• Simulates X-ray spectra of black hole X-ray binaries with returning radiation effects.
• Incorporates a disk+corona model, considering both thermal disk and reflection components.
• Uses a lamppost corona model and assumes Kerr spacetime, with a Novikov-Thorne disk.
• The reflection spectrum is produced by both direct corona radiation and returning radiation of the thermal and reflection components, calculated with the actual spectrum illuminating the disk.
• Self-consistently calculates the ionization parameter at each radial coordinate of the accretion disk.
