cds-question@unistra.frvariable-starsvisible-astronomybroad-band-photometryWe have used precise photometric and high-dispersion spectroscopic observations to study 11 gamma Doradus stars, 10 of them newly confirmed. Only five of these 11 gamma Doradus stars appear to be single; two are primaries of double-lined spectroscopic binaries, one is the secondary of a double-lined binary, two are primaries of visual binaries and, in the case of the double-lined binary (HD 86371), either or both components could be a pulsating gamma Doradus star. We have determined a preliminary orbital period of 5.32 days for the double-lined binary HD 41547. Several of the stars show spectroscopic line-profile and low-amplitude radial velocity variability indicative of pulsation. All 11 stars are photometrically variable with amplitudes between 4 and 94 mmag in Johnson B and periods between 0.38 and 1.86 days. The 11 stars have between two and five independent periods.2007AJ....133.1421Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/1421CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/450/715 : Differential uvby photometry of HD 218427 (Rodriguez+, 2006)J/A+A/456/261 : Differential uvby photometry of HD 239276 (Rodriguez+, 2006)J/A+A/472/241 : UV Flux distributions of gamma Dor stars (Gerbaldi+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/133/1421https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/133/1421http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/133/1421https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/133/1421https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/133/1421http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/133/1421GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/133/1421/table3 (Program, Comparison, and Check Stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/133/1421/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/133/1421/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/133/1421/table3?GETtext/xml+votable180.050000true23.4394960.62310970.005555555555555556Cone search capability for table J/AJ/133/1421/table6 (Derived Properties of gamma Doradus stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/133/1421/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/133/1421/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/133/1421/table6?GETtext/xml+votable180.050000true1.906149453.52654220.0055555555555555566/49 262 1888 2645 2813 2870 3088 3622 5258 5451 5724 6257 6424 6539 6706 7389 7759 7774 9293 10907 10988 11770 11917 12598 12695 13313 14103 14807 15019 15879 17398 17404 17491 18153 19235 19989 20125 20793 21275 21299 21352 21803 22269 23413 25685 25746 27091 27842 28025 28423 30318 30375 30677 31094 31763 31939 32233 33976 36832 39149 40400 42747 44364 45469 47928https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/133/1421?format=asciiOpticaldefaultJ/AJ/133/1421/table3Program, Comparison, and Check StarsrecnoRecord number assigned by the VizieR team.
