cds-question@unistra.frgiant-starsa-starsexoplanetsstellar-massesstellar-radiieffective-temperatureradial-velocityWe present the discovery of seven new planets and eight planet candidates around subgiant stars, as additions to the known sample of planets around "retired A stars". Among these are the possible first three-planet systems around subgiant stars, HD 163607 and HD 4917. Additionally, we present calculations of possible transit times, durations, depths, and probabilities for all known planets around subgiant (3<logg<4) stars, focused on possible transits during the TESS mission. While most have transit probabilities of 1%-2%, we find that there are three planets with transit probabilities >9%.2019AJ....157..149Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/157/149CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/182/97 : Radial velocities of multi-planet systems (Wittenmyer+, 2009)J/A+A/585/A134 : HD1461, HD40307, and HD204313 radial velocities (Diaz+, 2016)J/ApJS/225/32 : Extended abundance analysis of cool stars (Brewer+, 2016)J/ApJ/834/17 : Mass + radius of planets, moons, low mass stars (Chen+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/157/149https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/157/149http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/157/149https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/157/149https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/157/149http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/157/149GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/157/149/table2 (Stellar parameters for subgiants with known companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/157/149/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/157/149/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/157/149/table2?GETtext/xml+votable180.050000true26.232620.083150.0055555555555555566/0 174 679 957 2273 2456 2490 2577 4285 4286 4321 4429 5572 5985 6006 6687 7136 8785 9365 9753 10079 10548 10550 10772 11461 12306 12477 12612 13423 14416 14434 14568 15546 15549 16678 16884 17426 17507 18028 18172 18192 18315 18441 18947 18953 19669 21223 21406 22878 23322 25114 25446 26575 26707 26727 26938 27060 28085 28392 30170 30419 31606 34773 35958 36092 36390 36759 42318 42941 43639 48108 48109https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/157/149?format=asciidefaultJ/AJ/157/149/table2Stellar parameters for subgiants with known companionsrecnoRecord number assigned by the VizieR team.
