High Mass Death
Type II Supernovae
Neutron stars and BH
100
This happens when a high-mass star has an iron core.
What is fusion stops?
100
Causes shock wave that results in Type II supernova.
What is core bounce (core stops collapsing, because dense enough for atoms to repel, and bounces back)?
100

Property of a neutron star that gives it its name.

What is neutron degenerate?

200
Carries away energy quickly, so that fusion of each new element in the core of a supergiant is shorter than the last.
What is neutrino cooling?
200
Left after a Type II supernova explosion.
What is dense core of the star (neutron star or black hole)?
200

Emitted by a red giant and neutron star binary.

What is X-rays? This is called an X-ray binary.

300
High mass stars can't fuse iron because it _______ energy.
What is requires? Fusion of lighter elements MAKES energy.
300
These are made in supernova explosion.
What are new elements? Most elements heavier than iron are made this way.
300

Rapidly rotating neutron star.

What is a pulsar?

400
Starts core collapse in high mass stars.
What is no fusion? No fusion means no energy produces and no pressure to balance gravity in the core.
400
Triggered by supernova shock wave heating and compressing interstellar gas.
What is star formation?
400

Source of gamma ray bursts.

What are magnetars?

500
Physical properties of the core that increase as collapse accelerates.
What are gravity, density and temperature?
500
Type II supernova leave behind __________. Type Ia supernova leave behind __________.
What is neutron star and nothing?
500

Two ways black holes can form.

What are (1)Type II supernova and (2)binary accretion? (1) original star must be massive enough (2) binary of neutron star and giant, where neutron star pulls mass off giant
