BZ Crucis is the bright star between the open clusters NGC 4609 and Hogg 15

HD 110432 is a Be star in the south-east of Crux, behind the center of the southern hemisphere's dark 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, and has the variable star designation BZ Crucis. 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 Шаблон:Nowrap 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.[1]

Distance

The distance of Шаблон:Val published in the 2007 new Hipparcos reduction is over twice the distance of the Coalsack Nebula.[3] The distance from Gaia Data Release 2 is even further at Шаблон:Val.[4]
