Small Mass Stars

Front

What is the relationship between a star's mass and its lifespan?

Back

The lower a star's mass, the longer it lives.

Front

Which of the following is NOT a final stage of a star: red giant, white dwarf, neutron star?

Back

Red giant is NOT a final stage of a star.

Front

What is the biggest difference between a protostar and a main sequence star?

Back

Protostars do not engage in nuclear fusion.

Front

What is a red giant?

Back

A very large star of high luminosity and low surface temperature, thought to be in a late stage of evolution when no hydrogen remains in the core to fuel nuclear fusion.

Front

What are the main stages of a small mass star's life cycle?

Back

The main stages are: protostar, main sequence star, red giant, and white dwarf.

Front

How does a star's mass affect its evolution?

Back

Higher mass stars evolve faster and have shorter lifespans compared to lower mass stars.

Front

What happens to a star during the red giant phase?

Back

During the red giant phase, a star expands and cools, leading to a lower surface temperature and higher luminosity.

What is a white dwarf?

Back

A white dwarf is the remnant core of a star that has exhausted its nuclear fuel and shed its outer layers.
