Description


We perform a complete study of the HgMn binary HD 161701, including the determination of physical parameters and photospheric chemical abundances. We analyzed time series of high-resolution FEROS and HARPS spectroscopic observations in addition to a near-IR spectrum obtained with CRIRES. Radial velocity curves were combined with additional spectroscopic information to estimate absolute stellar parameters. A spectral separation technique was applied, which enabled us to conduct a detailed spectral analysis of both components. The primary is a HgMn star with overabundances of P, Mn, Ga, Y, Xe, and Hg. The secondary is an Ap star showing strong (2-5dex) overabundances of Sr, Y, and rare-earth elements. We detected line profile variations in both stellar companions, indicating a non uniform surface distribution of chemical composition. The secondary presents a remarkable chemical pattern with Ti and rare-earths pemanently facing the binary companion, and Fe concentrated on the far side. The primary star shows weak profile variations in Mn and Cr spectral lines. The coincidence of chemical spots with the position of the binary companion suggests a possible connection between the presence of the companion and the origin of chemical anomalies.
