Suppose That a Neutron Star of 2

Multiple Choice

Suppose that a neutron star of 2.9 solar masses is part of a binary star system in which the other star is a normal giant star. What would happen if 1 solar mass of material were transferred onto the neutron star from its companion?

A) The neutron star would explode as a supernova.
B) The neutron degeneracy pressure inside the neutron star would increase to balance the increased gravitational force in the neutron star.
C) The increased gravitational force would transform the neutrons into quarks, and the neutron star would reestablish equilibrium as a quark star of smaller diameter.
D) The neutron star would collapse and become a black hole.
