Question

The basic evolutionary sequence of a low-mass star like our Sun is:

a. White dwarf, planetary nebula, protostar, main sequence, red giant

b. Protostar, planetary nebula, main sequence, red giant, white dwarf

c. Main sequence, red giant, planetary nebula, white dwarf, protostar

d. Protostar, main sequence, red giant, planetary nebula, white dwarf

Answer 1

The basic evolutionary sequence of a low-mass star like our Sun is: main sequence, red giant, planetary nebula, white dwarf, protostar.

Step-by-step explanation:

The basic evolutionary sequence of a low-mass star like our Sun is: c. Main sequence, red giant, planetary nebula, white dwarf, protostar.

A star with a mass like that of the Sun evolves from the main sequence phase to become a red giant. After the red giant phase, it will expel its outer layers to form a planetary nebula. The remaining core of the star then becomes a white dwarf, which slowly cools over billions of years.
