25.2 Stellar Evolution

What is the process by which a star is born

• Core Reaches 10M K and fusion begins
• A cloud of dust and gas forms
• a red giant collapses
• a supernova occurs

IN Death descriptions of stars what type of star forms a red giant, which then collapses into a red dwarf and then forms a planetary nebula?

• low mass star
• medium-mass star
• massive star

IN Death descriptions of stars what type of star does not form a red giant, which then collapses into a red dwarf and then forms a planetary nebula?

• low mass star
• medium-mass star
• massive star

IN Death descriptions of stars what type of star blows up in a supernova explosion?

• low mass star
• medium-mass star
• massive star

IN Death descriptions of stars what type of star blows up in a supernova explosion?

• low mass star
• medium-mass star
• massive star

Which of these is a remnant of a supernova event: similar to a large atomic nucleus?

• black hole
• white dwarf
• neutron star

Which of these is a remnant of a low mass or medium mass star like our sun?

• black hole
• white dwarf
• neutron star

Which of these is a small dense object formed from the remnants of a star at least three times as massive as the sun?

• black hole
• white dwarf
• neutron star

all stars start out as:

• dust and gas
• variable
• main sequence
• black dwarf

All stars eventually run out of fuel?

• true
• false
