Query: Lowest Order Constrained Variational Calculation of Structure Properties
  of Protoneutron Star   We calculate the structure properties of protoneutron star such as equation
of state, maximum mass, radius and temperature profile using the lowest order
constrained variational method. We show that the mass and radius of
protoneutron star decrease by decreasing both entropy and temperature. For the
protoneutron star, it is shown that the temperature is nearly constant in the
core and drops rapidly near the crust.
