cds-question@unistra.frsubdwarf-starsstellar-distanceeffective-temperatureHot subdwarf B (sdB) stars are evolved, subluminous, helium-burning stars, most likely formed when red-giant stars lose their hydrogen envelope via interactions with close companions. They play an important role in our understanding of binary evolution, stellar atmospheres, and interiors. Within the sdB population, only a small fraction are known to exhibit pulsations. Pulsating sdBs have typically been discovered serendipitously in various photometric surveys, lacking specific selection criteria for the sample. Consequently, while individual properties of these stars are well-known, a comprehensive understanding of the entire population and many related questions remain unanswered. The introduction of Gaia has presented an exceptional chance to create an unbiased sample by employing precise criteria and ensuring a high degree of completeness. The progression of high-precision and high-duty cycle photometric monitoring facilitated by space missions such as Kepler/K2 and the Transiting Exoplanet Survey Satellite (TESS) has yielded an unparalleled wealth of data for pulsating sdBs. In this work, we created a dataset of confirmed pulsating sdB stars by combining information from various ground- and space-based photometric surveys. Utilizing this dataset, we present a thorough approach to search for pulsating sdB stars based on the current Gaia DR3 sample. Using TESS photometry, we discovered 61 new pulsating sdB stars and 20 variable sdBs whose source of variability remains to be determined through future spectroscopic follow-up observations.2024A&A...684A.118Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/684/A118CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/684/A118https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/684/A118http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/684/A118https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/684/A118https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/684/A118http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/684/A118GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/684/A118/tablea3 (Catalogue of all 256 known pulsating hot subdwarfs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/684/A118/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/684/A118/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/684/A118/tablea3?GETtext/xml+votable180.050000true328.6313-9.79170.0055555555555555566/103 463 664 764 2316 2641 2753 3928 4164 4228 4233 4271 4293 4297 4345 4630 4653 4663 4674 4709 4782 5655 5818 5858 6108 6292 6365 6507 6659 7052 7125 7811 8044 8128 8696 8830 8923 8994 9470 9624 9640 9644 9664 9690 9819 10007 10159 10188 10629 11029 11171 11560 11636 11813 12022 12200 12404 12921 13182 13442 13665 13767 13944 13999 14059 14396 14573 14575 14585 14756 14779 14825 14915 14921 14943 14957 14961 15108 15110 15126 15128 15132 15137 15148 15198 15285 15351 15854 16125 16150 16187 16430 16625 17323 17636 17726 18132 18344 18346 18601 18747 18766 18890 18966 19368-19369 19528 20223 20321 20474 20755 21000 21133 21734 21936 22002 22069 22169 22224 22304 22337 22452 22573 22640 22650 23009 23157 23244 23319 23421 23468 23510 23752 24106 24774 24907 24957 25108 25136 25153 25358 25582 25647 25713 25845 25945 26103 26112 26348 26517 26654 26762 26775 26883 27045 27379 27797 27839 28331 30549 31411 31491 31622 31627 32655 33064 33244 33387 33540 33828 33851 34237 34245 34414 34755 34986 35069 35150 35291 35355 35383 35460 35718 36191 36293 36587 37294 37486 38164 38369 38703 40506 40878 40902 41037 41296 41656 41693 41710 42256 42387 42965 43227 43297 44026 44463 44554 44825 44948 45169 45270 45386 45443 45632 45681 45753 45771 45803 45810 45949 45998 46079 46081 46149 46295 46430 46907 47514 47555 47716 48019 48137 48145 48344 48621 48752 48840 48933https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/684/A118?format=asciidefaultJ/A+A/684/A118/tablea3Catalogue of all 256 known pulsating hot subdwarfsSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
