Its story

21 Leonis Minoris is an elegant oddity: a white A-type star spinning on its axis in under twelve hours, deformed by its own momentum into a flattened spheroid. It also pulses as a Delta Scuti variable, beating across cycles of hours while sending its light across 92 light-years. The Lesser Lion, crouched between the Great Bear and the Lion proper, hides within its modest borders one of the fastest stellar gyroscopes we can study.
