Increased Gravitational Field of Neutron Star

How a neutron star has more gravity than its parent star?

The same amount of mass compressed into a smaller volume will give a bigger surface gravitational field. The reason is that the field decreases with distance, so on the more compact star with the smaller radius the field is stronger. At a fixed distance away, the field of the more or less compact stars will be the same. (We're ignoring relativistic effects here, not extremely important  for these stars.)
