Stellar Evolution 1
The first stage of stellar evolution.
What is a protostar?
Do high-mass or low-mass stars have longer lifespans?
Low-mass stars.
Does time slow or get faster at high speeds?
Slow
The type of black hole situated at the center of galaxies.
The portion of an H-R diagram in which our sun resides.
What is the Main Sequence?
This graph charts temperature with luminosity.
What is an H-R diagram?
The theoretical third class of stars.
What is a Population III star.
The center of a black hole.
What is a singularity?
Can you escape a black hole's gravitational pull?
Yes
What is the Hayashi Track?
The force that keeps neutron stars stable.
What is neutron degeneracy pressure?
A star that lacked sufficient energy to start fusion.
What is a brown dwarf?
This is present around the event horizon of a black hole.
What is an accretion disk?
This would happen to you if you went into a black hole.
What is spaghettification?
T^2 = a^3
What is Kepler's 3rd law?
The force that keeps white dwarfs stable.
What is electron degeneracy pressure?
The necessary mass for carbon fusion to occur in a star.
