Simbad
Other ID: BD+60 502
RA (J2000): 02 32 42.54
DEC (J2000): +61 27 21.58
distance (pc): 2300 (Massey et al. 1995)

Spectral type(s): O5.5III(f) + O7V

Multiplicity:
Confirmed binary, putative triple
Period(s): 442 d
Orbital solution: yes
Ref: Garmany & Massey (1981); De Becker et al. (2006a)

Quality flag (Q): II

Comments:
The primary object in this rather long period binary system presents an unexpectedly large minimum mass, suggesting that the primary object might be an unrevealed close binary (De Becker et al. 2006a). Anyway, the non-thermal radio emission should come from the interaction between the objects orbiting with a period of about 442 d. HD 15558 never benefited from a radio monitoring.
