Query: Grand Unification of Solutions of Accretion and Winds around Black Holes
  and Neutron Stars   We provide the complete set of global solutions of viscous transonic flows
(VTFs) around black holes and neutron stars. These solutions describe the
optically thick and optically thin flows from the horizon of the black hole or
from the neutron star surface to the location where the flow joins with a
Keplerian disk. We study the nature of the multiple sonic points as functions
of advection, rotation, viscosity, heating and cooling. Stable shock waves,
which join two transonic solutions, are found to be present in a large region
of the parameter space. We classify the solutions in terms of whether or not
the flow can have a standing shock wave. We find no new topology of solutions
other than what are observed in our previous studies of isothermal VTFs. We
particularly stress the importance of the boundary conditions and argue that we
have the most complete solution of accretion and winds around black holes and
neutron stars.
