(a) What supports a white dwarf from further collapse? (b) Whycanât a white dwarf have mass greaterthan 1.4M? (c) What supports a neutron star from collapsing underits own weight? (d) What willhappen to a neutron star whose mass is greater than 3M?
A star ending its life with a mass of four to eight times the Sun's mass is expected to collapse and then undergo a supernova event. In the remnant that is not carried away by the supernova explosion, protons and electrons combine to form a neutron star with approximately twice the mass of the Sun. Such a star can be thought of as a gigantic atomic nucleus. Assume r = aA1/3. If a star of mass 3.44 1030 kg is composed entirely of neutrons (mn = 1.67 10-27 kg), what would its radius be?
