An isolated star with the radius of the Sun (6.95 × 108 m) rotates on an axis through its centre once every 2.16 × 106 s. It collapses under gravity to form a much denser star with the radius of the Earth (6.38 × 106 m). For the purposes of this question, you may assume that no matter is lost from the star during its collapse. You may also treat the star as a homogeneous sphere before and after the...

Imagine we find a star that has the same radius as the Sun, but its temperature is 9.6 times greater. That star should be _____ times as luminous as the Sun. Suppose we find a planet with an orbital period of 200 days around a star with the same mass as the Sun, but only 75 percent as luminous. What is the planet’s semi-major axis, in AU?
