Stellar Explosion

What is a supernova?

• powerful and luminous stellar explosion that occurs during the final stages of a massive star's life

• A cloud that forms a new star

• a region of cosmic gas and dust formed from the cast-off outer layers of a dying star

• A black hole that has collapsed and exploded

The two main type of supernova are Type I and Type II.

• True

• False

What is the primary element produced in the intense heat and pressure of a supernova explosion?

• Carbon

• Boron

• Uranium

• Hydrogen

A shell of exploded debris surrounding the site of the explosion and expanding into space at a speed of thousands of kilometers per second

• Carbon-Detonation Supernova

• Core-Collapse Supernova

• Nucleosynthesis

What is a nova?

• nuclear fusion in the hearts of stars

• The formation of heavy elements by the capture of the helium nucleus.

• A star that suddenly increases greatly in brightness, then slowly fades over a period of a few months back to normal

• the numbers and the types of elements formed in stars.

What is the difference between a supernova and a nova?

• Supernovas are dimmer

• Supernovas are millions of times stronger than the nova.

• Supernovas don't produce anything

• Novas are millions of times stronger than the supernovas.

Where did the elements form?

• by absorption of neutrons

• Mitosis in stars

• In stellar nuclear synthesis; nuclear fusion in the hearts of stars

What is the neutron capture?

• light curves form Type I Supernova

• Glowing remains of a supernova

• The formation of heavier elements in the nuclei, by absorption of neutrons

• The iron core of a high mass star collapses
