Stellar evolution and observing the Universe

Easy

An astrophysicist compiles a dataset of main-sequence stars in a nearby stellar cluster to study stellar evolution.

Mass of star (relative to the Sun)	Main-sequence lifetime (years)
$60.0$	$3.0 \times 10^6$
$10.0$	$3.0 \times 10^7$
$2.0$	$1.2 \times 10^9$
$1.0$ (the Sun)	$1.0 \times 10^{10}$
$0.7$	$2.0 \times 10^{10}$
$0.2$	$1.0 \times 10^{12}$

State how the main-sequence lifetime of a star changes as the mass of the star increases.
