Question

Select the correct sequence of the life cycle of a star.

• A. $\text{Parent star}\to \text{Explosion}\to$\text{White dwarf}\rightarrow\text{Red giant}$
• B. $\text{Parent star}\to \text{Red giant}\to$\text{Explosion}\rightarrow\text{White dwarf}$
• C. $\text{Red giant}\to \text{Explosion}\to$\text{White dwarf}\rightarrow\text{Parent star}$
• D. $\text{White dwarf}\to \text{Explosion}\to$\text{Red giant}\rightarrow\text{Parent star}$

Answer 1

The correct option is B $\text{Parent star}\to \text{Red giant}\to$\text{Explosion}\rightarrow\text{White dwarf}$

A star's evolution and death depends on the mass of the star. For the stars with mass $\le 8$ times the mass of the Sun, the $\text{parent star}$ evolves into a $\text{red giant}$ in the later stages of its life. The red giant star $\text{explodes}$ violently and the star's core is left behind which is called a $\text{white dwarf}$.
Therefore, the correct order of a star's life cycle is: $\text{Parent star}\to \text{Red giant}\to$$\text{Explosion}\to \text{White dwarf}$
