Here we furnish a pseudo-Newtonian potential for accretion disk
modeling around
rotating central objects having a hard surface. Thus, the potential may
be useful
to describe the accretion disk around rotating neutron stars and
strange stars. The potential
can describe the general relativistic effects in accretion disks
properly, essentially
studying the relativistic hydrodynamics of disks. To
understand the fluid dynamics of the accretion disk around rotating
central objects with a hard surface, it is necessary to
incorporate the rotation of the central object,
which affects the inner edge of the disk. We derive our potential,
starting
from the Hartle Thorne metric. The potential can reproduce all the
essential properties of general relativity with a error at most,
for slowly rotating neutron/strange stars.
Key words: accretion, accretion disks / gravitation / relativity
