Abstract (from CDS):

HD 147395, a giant M2 star, was found to be a spectroscopic binary by the Mount Wilson astronomers some time ago, but its orbit remained unknown so far. Radial velocity observations carried out at the Observatoire de Haute-Provence with the CORAVEL spectrovelocimeter permitted us to obtain the orbital elements of this binary. They are as follows: P=335.537days; T=4448335.0JD; ω=336.9deg ; e=0.235; K=16.87km/s; V0=-20.12km/s; a1sini=75.67Gm; f(M)=0.154M☉. The spectral type of the primary, and the f(M) value, lead to M2≥1.0±0.2M☉ for the mass of the unseen companion. According to the color indices B-V and U-B of the system, the secondary star should be a F5V. We estimate at 1.25±0.1UA the mean linear separation of the components; nevertheless, both the distance of this binary (d∼275pc) and the expected value of {DELTA}m seem too important for the system to be resolved by interferometry.
