Beta Crateris, Latinized from β Crateris, is a binary star[3] system in the southern constellation of Crater. It is visible to the naked eye with an apparent visual magnitude of 4.46.[2] Based upon an annual parallax shift of 9.59 mas as seen from Earth, it is located around 340 light years from the Sun.
This is an astrometric binary[13] star system with an orbital period of 6.0 years and a projected separation of 8.3 AU. The orbit has an estimated semimajor axis of 9.3 AU.[3] The primary, component A, is listed as an A-type giant star with a stellar classification of A2 III.[3][13][10] However, Houk and Smith-Moore (1988) give a main sequence classification of A1 V,[14] while Abt and Morrell (1995) list it as a subgiant star with a class of A2 IV.[15] The spectrum shows enhanced barium, possibly as a result of a previous mass transfer event.[8]
The companion, component B, is a white dwarf[10] of class DA with an effective temperature of 36,885 K that has been cooling down for around four million years.[11] It has an unusually low mass, 43% that of the Sun, suggesting that the white dwarf progenitor may have transferred matter to its companion. Alternative scenarios require either the evolution of a triple star system, or a binary system with highly eccentric orbit resulting in grazing interactions.[3] The dwarf is a source of X-ray emission.[16]
