1. The problem statement, all variables and given/known data About neutron stars we can say that: a) They are newborn stars b) They are generated when a Solar-type star dies c) They are generated when a very massive star dies d) They are in the main sequence 2. Relevant equations None. 3. The attempt at a solution I'm quite sure that a) and d) are false because a neutron star is a type of stellar remnant. I think that the correct answer would be c), that is, only very massive stars can produce a neutron star. I'd be very happy if anyone could confirm this. Thanks in advance!
