Stellar Evolution

Stars can take different paths due to their initial . . .

• 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

What stage fills in the blank. Nebula --> Main sequence --> red giant --> ______________ --> white dwarf --> black dwaft

• supergiant

• Variable Star

• black hole

• supernova

When a nebula heats up, a "baby" star forms in the middle. It is called a

• supernova
• supergiant
• white dwarf
• protostar

Which of the following is NOT a final stage of a star. 

• black hole
• black dwarf
• neutron star
• red giant

In this stage, a star spends most of its life. Hydrogen is fused into helium at a temperature of millions of degrees.

• nebula
• protostar
• main-sequence
• supergiant

Low mass stars expand into what after using up the hydrogen in their core

• red giants
• supergiants
• white dwarfs
• protostars

This is a young star that glows as gravity brings it together

• Nebula
• Protostar
• Main-sequence star
• Red giant

The final stage of a low mass star is a 

• neutron star
• nebula
• black hole
• black dwarf
