100

In a binary pair, the star that evolves to a white dwarf first.

What is the more massive star?

100

The reason stars leave the main sequence.

What is hydrogen is used up in the core?

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)?
200

The quick burn of a layer of hydrogen on a white dwarf, collected from a giant companion.

What is a nova?


200

This stays the same as a high-mass star expands and cools after leaving the main sequence.

What is luminosity?

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)?
300

Collapse, burning, and explosion of a white dwarf pushed over the Chandrasekhar limit by a giant companion.

What is a Type Ia Supernova?

300

Direction high mass stars move on the HR diagram after leaving the main sequence?

What is right?

300
High mass stars can't fuse iron because it _______ energy.
What is requires? Fusion of lighter elements MAKES energy.
300
Type II supernova leave behind __________. Type Ia supernova leave behind __________.
What is neutron star and nothing?
400

A luminous event between a white dwarf and red giant that can reoccur multiple times in the same system.

What is a nova?

400

Type of fusion occurring in the core of supergiants when they first leave the main sequence.

What is helium fusion?

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.
500

Two possible outcomes of a low-mass binary star system.

What are 2 white dwarfs or a Type 1a Supernova and a white dwarf?

500

A new one is added every time a new element begins fusing in the core of a supergiant.

What is a fusion shell? Supergiants can have many different types of fusion shells.

500

Physical properties of the core that increase as collapse accelerates.

What are gravity, density and temperature?
