Exam 16: Stars in the Slow Lanelow-Mass Stellar Evolution

Once the core of a low-mass main-sequence star runs out of hydrogen,fusion in the star stops until the core temperature is high enough for helium fusion to begin.

A main-sequence star is unique because

A nova is the result of which explosive situation?

The gas in a planetary nebula is composed of

Binary stars can evolve to become novae and supernovae because slight differences in mass can mean large differences in main-sequence lifetimes.

When a star depletes its core supply of hydrogen,__________ dominates in the core and __________ dominates in the atmosphere.

If a main-sequence star's core temperature increased,fusion reaction rates would decrease because the protons would be moving faster.

A Type I supernova is as luminous as 10 billion Suns.

A star like the Sun will lose about __________ of its mass before it evolves to become a white dwarf.
