End State of a Star

According to our present theories of stellar evolution, our sun will change next into

• a white dwarf.

• a black hole.

• a supernova.

• a red giant.

The explosion of a massive star near the end of its life is known as a

• nova

• supernova

• pulsar

• nebula

According to this flowchart, the sun will become

• hotter and brighter in stage 2, then cooler and dimmer in stage 3.

• cooler and dimmer in stage 2, then hotter and brighter in stage 3.

• hotter and dimmer in stage 2, then cooler and brighter in stage 3.

• cooler and brighter in stage 2, then hotter and dimmer in stage 3.

A black hole

• forms after the death of a high mass star because of high gravitational attraction.

• forms after the death of a high mass star when all gases drift into space.

• forms when a low to medium mass star runs out of "fuel."

Based on the HR diagram white dwarfs are hot and dim.

• True

• False

A super giant would most likely go through this towards the end of it's life.

• Black hole

• Supernova.

• Nebula

• Planetary nebula

The reason a black dwarf is not "bright."

• No more fusion.

• Only Carbon Fusion.

• Only Helium fusion.

What is the final stage of a low-mass star like our Sun?

• White dwarf

Which of the following is a possible end state for a high-mass star?

• White dwarf

• Red giant
