SIMBAD data

HD 53367 is a triple star system in the constellation of Monoceros. The primary star was identified as a variable Herbig Ae/Be star in 1989. [6] Its companion, spectroscopically discovered in 2006, is a pre-main-sequence star with an average separation of 1.7 AU. [1] The star system is embedded in the extended nebula IC 2177.

The binary HD 53367A is part of the hierarchical triple star system RST 3489, with an additional Herbig Ae/Be star HD 53367B of spectral class B1Ve at a projected separation of 0.6″. All stars in the system belong to the star-forming CMa OB1 association. [6] The Hipparcos, [9] Gaia Data Release 2, [10] and Gaia Data Release 3 [2] parallax values for HD 53367A are highly discrepant, but the system is thought to be about 1,000 parsecs away. [11] [7]

HD 53367A is a very young and gas-rich system, with most of the gas still obscuring the secondary component HD 53367Ab. [1]
