BlackTom AI · Accepted Answer

The question asks which objects may be produced by a supernova explosion, allowing for multiple correct choices.

Option a. Neutron stars. This is a correct possibility: when a massive star explodes in a core-collapse supernova, the remaining core can become a neutron star if the mass is in the right range, supported by neutron degeneracy pressure.

Option b. Brown dwarfs. This is not produced by a supernova. Brown dwarfs are substellar objects that never sustain hydrogen fusion and form through direct collapse of gas clouds, not as remnants of stellar explosions.

Option c. Black holes. This is also correct for many core-collapse supernovae: if the stellar remnant is too massive to be stabilized as a neutron star, it collapses into a black hole.

Option d. White dwarfs. White dwarfs are the end state of low- to intermediate-mass stars that do not undergo core-collapse supernovae; they form from stars that shed their outer layers and leave behind a degenerate carbon-oxygen core, so this is not produced by a supernova explosion.

Option e. Supergiants. Supergiants are a stellar evolutionary stage of massive stars before they explode; they are not produced by a supernova explosion themselves. Rather, a star in the supergiant phase may eventually explode as a supernova.

In summary, the objects that can be produced directly as remnants of a supernova explosion are neutron stars and black holes, whereas brown dwarfs, white dwarfs, and supergiants are not produced by the explosion itself (though supergiants can precede a supernova).
