Caph (Beta Cassiopeiae)
In terms of its evolution, Caph is currently in the Hertzsprung Gap, a relatively short-lived stage (lasting a few tens of millions of years), in which its core will shrink while its outer layers expand to become a red giant. It is also unusual in being a Delta Scuti star – in fact, the brightest of this type – varying in brightness by about 6% over a 2.5-hour period. It has a small companion, about which little is known, in a 27-day orbit.
