Detailed Description
A geometrically thick, radiatively thin accretion structure modeling an ion torus as described by Rees et al. 1982, as far as the radiation is concerned. The gas dynamics is taken from Abramowicz et al. 1978 "Polish Doughnuts" paper, hence the class name. Polish doughnuts are optically thick so strictly speaking, the class name is misleading. The angular momentum l=L/E is assumed constant in the full interior of the doughnut.
There are two flavors of polish doughnuts:
- Roche lobe filling, that is, they are filled up to the cusp radius (rinner=rcusp) thus allowing accretion onto the compact object. See lambda() function below.
- Defined from a value of the inner radius specified by the user, so can be typically smaller than the Roche-lobe-filling doughnut, and thus non-accreting. See angmomrinner() function below.
