Which object forms when a collapsing stellar core is between 1.4 and 3 solar masses?
Answer
A neutron star
When a high-mass star experiences a core collapse during a supernova, the remaining material is compressed to extreme densities. If the mass of the remnant falls within the range of approximately 1.4 to 3 times that of the Sun, the gravity is strong enough to crush the core into a neutron star. This object is composed almost entirely of neutrons and represents one of the densest states of matter in the universe.
