The star Tau Ceti's mass is 1.6 ✕ 1030 kg, its radius is 5.5 ✕ 105 km, and it has a rotational period of approximately 34 days. If Tau Ceti should collapse into a white dwarf of radius 7.5 ✕ 103 km, what would its period (in s) be if no mass were ejected and a sphere of uniform density can model Tau Ceti both before and after?
