cds-question@unistra.frmultiple-starsexoplanetsradial-velocityvisible-astronomyRadial velocity searches may lead to detection of exoplanets at large orbital separations only if long-enough time-series of data are available. Therefore publication of precise measurements collected in the past is very valuable even if not successfully completed with a definitive detection. Here we present 309 precise ({sigma}_RV_~5-7m/s) multi-epoch radial velocities for 28 stars observed with the Hobby-Eberly Telescope and its High Resolution Spectrograph between 2004 and 2013. Based on the observations gathered we present a low mass companion (m_p_sini=10.6M_J_ in 1887.76+/-0.01d, 4.65au orbit with e=0.59+/-0.01 ) to a K giant BD+37 3172 (M=3.75+/-0.86 M_{sun}_), and a planetary mass companion (m_p_sini=0.55M_J_ in 123.05+/-0.04d, 0.55 au orbit with e=0.73+/-0.03) to a K giant BD+42 2315 (M=1.38+/-0.30 M_{sun}_). We also present two preliminary detections of new spectroscopic binaries: BD+56 2957 (K5) and HD 236555 (G5).2023AcA....73..291Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/73/291CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/73/291https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/73/291http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/73/291https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/73/291https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/73/291http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/73/291GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AcA/73/291/table1Summary of basic data on target starsrecnoRecord number assigned by the VizieR team.
