cds-question@unistra.frspectroscopic-binary-starsvariable-starsvisible-astronomybroad-band-photometryradial-velocityNew spectroscopic and photometric observations of HD 144110 have been used to obtain an improved orbital element solution and determine some basic properties of the system. This chromospherically active, double-lined spectroscopic binary has an orbital period of 1.6714012days and a circular orbit. We classify the components as G5 V and K0 V and suggest that they are slightly metal-rich. The photometric observations indicate that the rotation of HD 144110 is synchronous with the orbital period. Despite the short orbital period, no evidence of eclipses is seen in our photometry.2005AJ....130..794Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/130/794CatalogResearchIsServedByTAP VizieR generic servicerelated-toV/76 : Chromospherically Active Binaries (Strassmeier+ 1993)J/AJ/105/2265 : Spectroscopy and photometry of HD 212280 (Fekel+ 1993)J/AJ/129/1669 : BV photometry of HD 37824, HD 181809, and HD 217188https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/130/794https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/130/794http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/130/794https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/130/794https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/130/794http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/130/794GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/130/794/table1Radial velocities of HD 144110recnoRecord number assigned by the VizieR team.
