GR accretion disk around a black hole.
XSpec model.
General Relativistic Accretion Disk model around a Schwarzschild black
hole. Inner radius is fixed to be 3 Schwarzschild radii, and the
energy conversion efficiency is 0.057. See Hanawa, T., 1989, ApJ,
341, 948 and Ebisawa, K. Mitsuda, K. and Hanawa, T. 1991, ApJ, 367,
213.
xsgrad Parameters
| 1 | D | distance
(kpc) |
| 2 | i | disk inclination
angle (degrees); 0 for face-on |
| 3 | Mass | mass of the
central object (solar units) |
| 4 | Mdot | mass accretion
rate (1e18 g/s) |
| 5 | Tclef | spectral
hardening factor, Tcol/Teff. Should be greater than 1.0, and
considered to be 1.5-1.9 for accretion disks around a stellar-mass
black hole. See, e.g. Shimura and Takahara, 1995, ApJ, 445,
780 |
| 6 | norm | normalization
factor; should be fixed to 1. |
