Gaia Astrometry and MIKE+PFS Doppler Data Joint Analysis Reveals that HD 175167b is a Massive Cold Jupiter.

Abstract (from CDS):

HD 175167b is a cold (Pb ∼ 1200 days) Jupiter with a minimum mass of ${M}_{p}\,\sin \,i=7.8\pm 3.5\ {M}_{J}$ orbiting a Sun-like star, first discovered by the Magellan Planet Search Program based on MIKE observations. Through a joint analysis of the MIKE data and the Gaia two-body orbital solution, Winn found a companion mass of Mp = 14.8 ± 1.8 MJ and suggested that it might be better designated as a brown dwarf. Additional publicly available radial velocity data from Magellan/PFS better constrains the model, and reveals that the companion is a massive cold Jupiter with a mass of Mp = 10.2 ± 0.4 MJ and a period of Pb = 1275.8 ± 0.4 days. The planet orbit is inclined by i = 38.°6 ± 1.°7 with an eccentricity of 0.529 ± 0.002.
