HD 43162 is a star system consisting of a young Solar analog star and three orbiting red dwarfs. It is located about 54.5 light-years (16.7 parsecs) away in the southern constellation of Canis Majoris, making it one of the closest quadruple star systems. It has the variable star designation V352 Canis Majoris (sometimes abbreviated to V352 CMa). With an apparent magnitude of 6.366, it is barely visible to the naked eye under dark skies far from city lights.

Stellar components

[edit]

HD 43162 A

[edit]

Anomalous carbon abundance Variability

Photometric data from the Hipparcos catalog indicates that the photometric variability of the star may be caused by an unresolved companion, which, if true, would make this component a binary system (Aa/Ab) itself.[5]

HD 43162 B (2MASS J0613−2352 AB)

[edit]

HD 43162 B, also known as 2MASS J06134539−2352077, was reported to be a co-moving companion to HD 43162 A in 2013, located at a separation of 24 arcseconds (410 AU) from the primary star.[5] This object had been discovered to be a binary during the Astralux Large M-Dwarf Multiplicity Survey in 2012,[8] and the two components have been determined to be red dwarfs.

The larger component (2MASS J0613−2352A) has a spectral type of M3.5 and a temperature of 3,265 K, while the smaller (B) has the spectral type M5.0 and a temperature of 3,180 K.[9] The two stars have a total mass of 0.57 M☉ or 0.42 M☉, with a mass ratio of 0.63 : 0.37. They orbit each other with a period of 13 years[10] at a distance of 3.91+0.83
−0.11 AU or 4.62+0.06
−0.04 AU, with a high eccentricity of 0.77+0.10
−0.11 or 0.65±0.01. Due to the possible presence of missing mass, potential remains for the existence of another unseen body within the system.[11]

They are likely part of the Argus Association, which places their age at 45±5 Ma.[11]

HD 43162 C

[edit]

In 2010, the M4-type red dwarf 2MASS J06134717−2354250 was found to be a co-moving companion to HD 43162 A and was initially designated HD 43162 B,[12] before it was re-designated HD 43162 C in 2013.[5] It is situated 164 arcseconds away from the primary, which corresponds to a distance of 2,740 AU.[5]
