Paczynski realized that a properly chosen gravitational potential may accurately model (in a ``pseudo Newtonian'' theory) general relativistic effects that determine the motion of matter near a nonrotating black hole. Paczynski's choice, known today as the ``Paczynski-Wiita potential'', proved to be very practical. It was used by numerous researchers in the black-hole accretion theory and became a standard tool in relativistic astrophysics. The model is an example of Paczynski's admired ability… CONTINUE READING
