Question

Which of the following would you expect to see in the death of a star that is less than 0.5 solar mass

A: supernova
B: planetary nebula
C: white dwarf
D: red giant

Answer 1

The answer is; C

When such as star begins to exhaust its fuel, it expands into a red giant  because it begins to burn helium rather than hydrogen. When the helium is exhausted and it cannot burn carbon, a planetary nebula is formed when the fuel is exhausted. A white dwarf is left behind as remnants which begins to cool down over millions of years.

Answer 2

Answer:

The correct answer is option C: white dwarf .

Explanation:

 The white dwarf is a type of compact star that is generated when nuclear fuel with a mass of less than 9.10 solar masses has been used up.

This is a stage, and through this stage all the stars will pass, including the Sun (Remember that the sun is a star). This type of star is one of the most abundant.

Given this information we can say that the correct answer is option C.
