Query: Spherical Accretion onto Neutron Stars Revisited: Are Hot Solutions
  Possible ?   Stationary, spherical accretion onto an unmagnetized neutron star is here
reconsidered on the wake of the seminal paper by Zel'dovich \& Shakura (1969).
It is found that new ``hot'' solutions may exist for a wide range of
luminosities. These solutions are characterized by a high temperature,
$10^{9}\div 10^{11}$ K, and arise from a stationary equilibrium model where the
dominant radiative mechanisms are multiple Compton scattering and
bremsstrahlung emission. For low luminosities, $\mincir 10^{-2} \ L_{E}$, only
the ``cold'' (\`a la Zel'dovich and Shakura) solution is present.
