Caph
(kaf )
Beta Cassiopeiae
Names For This Star
This star is also known as Chaph, Kaff, or Al Sanam al Nakah.
The Arabs sometimes referred to the area of Cassiopeia as Kaff' al Hadib, "The Hand Stained with Henna." The usual name of the star, Caph, derives from this traditional name for the constellation.
Al Sanam al Nakah is "The Camel's Hump," reflecting another traditional version of Cassiopeia as a camel.
Description of the Star
Caph is a yellowish F2III-IV giant to subgiant star. The luminosity is 130 times that of the sun. The spectrum indicates that Caph is a binary star with an orbital period of 27 days, but there is little information available on the companion.
