cds-question@unistra.frvariable-starsphotometryradial-velocityWe have carried out a photometric survey of a complete, volume-limited sample of {gamma} Doradus candidates. The sample was extracted from the Hipparcos catalog and consists of 114 stars with colors and absolute magnitudes within the range of known {gamma} Doradus stars and that also lie within a specified volume of 266600pc^3^. We devoted one year of observing time with our T12 0.8m automatic photometric telescope to acquire nightly observations of the complete sample of stars. From these survey observations, we identify 37 stars with intrinsic variability of 0.002mag or more. Of these 37 variables, 8 have already been confirmed as {gamma} Doradus stars in our earlier papers; we scheduled the remaining 29 variables on our T3 0.4m automatic telescope to acquire more intensive observations over the next two years. As promising new {gamma} Doradus candidates were identified from the photometry, we obtained complementary spectroscopic observations of each candidate with the Kitt Peak coude feed telescope. Analysis of our new photometric and spectroscopic data reveals 15 new {gamma} Doradus variables (and confirms two others), 8 new {delta} Scuti variables (and confirms one other), and 3 new variables with unresolved periodicity. Therefore, of the 114 {gamma} Doradus candidates in our volume-limited sample, we find 25 stars that are new or previously known {gamma} Doradus variables. This results in an incidence of 22% for {gamma} Doradus variability among candidate field stars for this volume of the solar neighborhood. The corresponding space density of {gamma} Doradus stars in this volume of space is 0.094 stars per 103pc^3^ or 94 stars per 106pc^3^. We provide an updated list of 86 bright, confirmed, {gamma} Doradus field stars.2011AJ....142...39Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/142/39CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/472/241 : UV Flux distributions of gamma Dor stars (Gerbaldi+, 2007)J/AJ/133/1421 : BV differential photometry of 11 gamma Dor stars (Henry+, 2007)J/A+A/499/967 : Long-term monitoring of {gamma} Dor stars (Cuypers+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/142/39https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/142/39http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/142/39https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/142/39https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/142/39http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/142/39GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/142/39/table2 (Volume-limited sample of 114 gamma Doradus candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/142/39/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/142/39/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/142/39/table2?GETtext/xml+votable180.050000true5.971585360.96141420.0055555555555555566/41 351 508 738 890 1362 1412 1594 1787 1792 1948 1977 2370 2645 2949 3047 3249 3340 4124 4238 4465 4776 5770 6203 6424 6442 6634 6713 6716 6830 6948 7136 7154 7332 8274 8592 9212 9425 9675 9861 9913 10077 10228 10467 10613 10626 10725 10822 11176 11335 12598 12645 12686 12735 13313 13485 13743 14359 14390 14851 14970 15019 15417 15418 17398 17893 18034 18318 18423 18963 19175 19600 20023 21458 21803 21927 22434 22874 23392 23525 23592 23668 23676 24399 25685 25686 25804 25868 26443 26780 27027 27091 27249 27850 27887 27909 28278 28350 28396 28482 28517 28585 28618 29791 30337 30375 30874 31149 31160 31373 31391 32025 32536 32754https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/142/39?format=asciiOpticaldefaultJ/AJ/142/39/table2Volume-limited sample of 114 gamma Doradus candidatesrecnoRecord number assigned by the VizieR team.
