PPT-Where are the Low-mass Neutron Stars?

Frederick Seward ABSTRACT Neutron stars are predicted to be stable over the mass range 01 to 3M At 14 M 98 of the mass is in a core with supernuclear density and 12 forms a thin crust and atmosphere As mass decreases the fraction of mass in the crust increases until at .

As human beings go through cyclic lives, maturing from birth to maturity to old age, stars also follow a series of stages from their creation until death. Stars follow varying sequences of change depending greatly on their solar mass, or their gravitational weight . Frederick Seward. ABSTRACT.
