Z CMa


Coordinates (2000.0) : R.A. = 07h03m43.2s, Decl. = -11°33'06"

Z CMa (HD 51370) is a young visual binary system consisting of a 12 Ms Herbig AeBe star and a 3 M FUOri companion of an age of 0.3 Myr (Alonso-Albi et al. 2009). Both components
are surrounded by active accreting disks. Associated with the binary system is a giant parsec-size jet (Poetzel et al. 1989). L = 1300 Ls, R = 13 Rs and Teff = 10 000K for the
Z CMa SE FUOri component and L = 2400 Ls, R = 1690Rs, and TBB = 980K for the near-sinfrared Z CMaNW component
