Analysis of the public HARPS/ESO spectroscopic archive

Aims. We use the recently published database (Trifonov et al. 2020) of radial velocities (RVs) that were derived from fifteen years HARPS/ESO observations to search for planet candidates. Methods. For targets with sufficient RV data, we apply an automated algorithm identify significant periodic signals and fit a Keplerian model orbital estimates. also auxiliary data stellar-activity indices compare our findings existing literature, detect have no counterpart in activity timeseries. The most convincing are then manually inspected designate additional false detection, focusing on long-period (P > 1 000 d) massive candidates around FGK dwarf stars. Results. two Jupiter analogs, orbit slightly evolved F8V star HD 103891 Solar-like 105779. nested sampling derive their parameters, find periods be 1919 +/- 16 d 2412 54 d, while minimum masses 1.44 0.02 M Jup 0.64 0.06 , respectively. While b is eccentric (e = 0.31 0.03), 105779 likely circular < 0.16). Conclusions. With astrometric signatures 59 42 $\mu$as, join growing sample planets whose exact may soon Gaia astrometry. This finding highlights importance long-term surveys study planetary occurrence beyond snow line
