Low and Medium Mass Stars
The remains of a star's core
What is a White Dwarf
The shortest stage of the cycle.
What is supernova
14.5 billion years
Where do stars form?
What is Nebula
The longest part in the low/medium mass star's life cycle.
What is the Main Sequence
why is the high mass stars life-cycle so short?
What is "it fuses hydrogen more quickly"
The scientific theory with the MOST evidence for how the universe began is:
The Big Bang Theory
: The small, dense remains of a high-mass star after a supernova.
What is Neutron star
What do we call a "failed" star?
a brown dwarf
The first part in the star's whole life cycle
What is a star-forming nebula
The part of the cycle where a new protostar can ~possibly be formed
What is Super Nova
The most common element in the universe is:
Hydrogen
The white dwarf is made of the previous star's core. T/F
True
The only low-mass stars which can ever gain enough mass to go supernova are _____________.
binary stars
(remember: they can steal hydrogen from their neighbor)
The last, most destructive part in the life cycle in high mass stars
What is Black hole
This is what collects all the dust/debris together to form stars and planets.
What is gravity.
Will the Sun ever become a supernova?
No.
A low mass star will end its life as a:

(recall: this was part of the COBE mission)
The color of a Star depends on its:
