HD 110432 is a Be star in the constellation Crux, behind the southern Coalsack Nebula. It has a stellar classification of B1IVe, which means it is a
subgiant star of class B that displays emission lines in its spectrum. This is a variable star of the Gamma Cassiopeiae type,
indicating it is a shell star with a circumstellar disk of gas about the equator. It is not known to be a member of a binary system, although it is probably a member of the open cluster NGC 4609. This star is moderately luminous in the X-ray band, with a variable energy emission of in the range 0.2−12 keV. The X-ray emission may be caused by magnetic activity, or possibly by accretion onto a white dwarf companion.〔
