Supernova Remnants and Nuetron Stars

What is a supernova remnant?

• A new star formed from a supernova

• The remains of the outer atmosphere of a massive star that has exploded

• A black hole formed from a supernova

• The core of a star left after a supernova

What happens when a supernova remnant collides with the interstellar medium?

• It causes the supernova remnant to disappear

• It triggers the formation of new stars

• It creates a neutron star

• It forms a black hole

What is a neutron star primarily composed of?

• Electrons

• Protons

• Neutrons

• Atoms

What is the Chandrasekhar limit?

• The maximum size a supernova remnant can reach

• The limit of mass for a white dwarf to remain stable

• The minimum mass a star needs to become a black hole

• The maximum mass a neutron star can have

What is the Crab Nebula?

• A black hole

• A newly formed star

• A supernova remnant

• A type of neutron star

What is the role of neutrinos in a supernova explosion?

• They help force the envelope of an exploding star away into space

• They stabilize the neutron star

• They form new stars

• They create black holes
