What kinds of elements do low mass stars make?

Usually only Helium and maybe eventually Carbon.

200

What determines how a star dies?

Its mass
200
Group of stars is brighter than the red giants?

Supergiants

200

What two elements combine in fusion to form Helium?

Two heavy hydrogen atoms

200

What color was Nelson's hair

Brown

300

What stage do low mass stars stop doing fusion?

During the white dwarf stage or stage 5

300

The biggest stars in the universe with a mass greater than 20x our suns mass will die with what stage?

A supernova and end in a black hole?
300

What two characteristics does an HR diagram tell us about a star?

Luminosity and Temperature

300

What element(s) is our sun making now and is there anything else made?

Helium and radiation

300

The farthest stars from Earth might already be dead, True or false?

True, the light has just been traveling to us for a very long time.

400

Low mass stars are always in the main sequence of stars. True or false?

False. They can expand into Red Giants

400

True or false, all stars end up being a black hole.

False

400

Which group of stars has stars from each temperature group?

Main sequence

400

What stars produce the most types of elements?

The supergiants

400

What is the closest star to Earth

The sun

500

Why do low mass stars live longer that high mass stars?

High mass stars are hotter and can burn through their fuel very fast, meaning they will die quickly.

500

Why are high mass stars able to make more types of elements?

Because they have a higher pressure and heat.

500

Tell me the three groups of stars that our sun will be part of, in order of age (youngest to oldest stages)

Main sequence, Red Giant, white dwarf

500

True or false, the heaviest elements like gold or uranium are made during a supernova.

True, there is so much pressure and heat that fusion can happen as the supernova is happening.
