Ch. 23 Flashcards
1
Q
White Dwarf
A
- Pressure from gravity from high density is balanced by electron degeneracy
- The smaller, the more massive
2
Q
Chandrasekhar Limit
A
Maximum mass that a star can end its life with and still become a white dwarf → 1.4 Msun
3
Q
Explosive Finish
A
Stars with masses > 150Msun die explosively → outer layers bounce off while inner layers collapse
4
Q
Type II Supernova
A
1 single massive star exploding
5
Q
Type Ia Supernova
A
Ignited when a lot of material is dumped on degenerate white dwarfs
6
Q
Pulsar
A
- Pulsating radio source
- Densest matter in universe
- 600 rotations per second
- Dense neutron star prevents parts spilling out
7
Q
Neutron Star
A
A compact object of extremely high density composed almost entirely of neutrons
