• temperature
• mass
• brightness
• color

All stars start as gas and dust in a(n)

• nebula
• black hole
• red giant
• black dwarf

After the main sequence, a low mass star becomes a

• black dwarf
• protostar
• red giant
• supergiant

After the main sequence, a high mass star becomes a

• black dwarf
• protostar
• red giant
• supergiant

The final stage of a low mass star is a 

• neutron star
• nebula
• black hole
• black dwarf

After a supergiant, a high mass star explodes and forms a

• supernova
• red giant
• black hole
• planetary nebula

A high mass star can end as this stage, which is so dense that not even light can escape!

• black dwarf
• white dwarf
• supernova
• black hole
