cds-question@unistra.frspectroscopic-binary-starsvariable-starsvisible-astronomybroad-band-photometryWe have obtained spectroscopy and photometry of three chromospherically active, single-lined spectroscopic binaries: HD 37824 (V1149 Ori), HD 181809 (V4138 Sgr), and HD 217188 (AZ Psc). * HD 37824 has a circular orbit with a period of 53.57 days. Its primary is a K0 III star, while the secondary is likely a G or K dwarf. * HD 181809 has an orbit with a period of 13.04667 days and a low eccentricity of 0.040. The primary has a spectral type of K0 IIIIV, and its secondary is probably an M dwarf. * The orbit of HD 217188 has a period of 47.1209 days and a moderately high eccentricity of 0.470. The spectral type of the primary is K0III, while the secondary is likely an M dwarf. All three systems are estimated to have near solar iron abundances. Photometric observations spanning 15-16 years for all three stars yield mean photometric periods of 53.12, 59.85, and 90.89 days for HD 37824, HD 181809, and HD 217188, respectively.2005AJ....129.1669Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/129/1669CatalogResearchIsServedByTAP VizieR generic servicerelated-toV/76 : Chromospherically Active Binaries (Strassmeier+ 1993)J/AJ/105/2265 : Spectroscopy and photometry of HD 212280 (Fekel+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/129/1669https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/129/1669http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/129/1669https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/129/1669https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/129/1669http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/129/1669GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/129/1669/table4Photometric observations of HD 37824recnoRecord number assigned by the VizieR team.
