When the sun leaves the main sequence it will turn into a red giant. About how big will the radius be?

The mass limit for a white dwarf is

Sunspots are dark regions found on the suns’

Cepheid variable stars are important to astronomy because

Use the graph below to describe the 4 basic life cycle steps of a low mass star by selecting the color of each region marked on the H-R Diagram. (The black diagonal line is considered one of the answer choices)
