cds-question@unistra.frmultiple-starsexoplanetsphotometryvisible-astronomyradial-velocityWhile the sample of confirmed exoplanets continues to grow, the population of transiting exoplanets around early-type stars is still limited. These planets allow us to investigate the planet properties and formation pathways over a wide range of stellar masses and study the impact of high irradiation on hot Jupiters orbiting such stars. We report the discovery of TOI-615b, TOI-622b, and TOI-2641b, three Saturn-mass planets transiting main sequence, F-type stars. The planets were identified by the Transiting Exoplanet Survey Satellite (TESS) and confirmed with complementary ground-based and radial velocity observations. TOI-615b is a highly irradiated (~1277F_{Earth}_) and bloated Saturn-mass planet (1.69^+0.05^_-0.06_R_Jup_ and 0.43^+0.09^_-0.08_M_Jup_) in a 4.66 day orbit transiting a 6850K star. TOI-622b has a radius of 0.82^+0.03^_-0.03_R_Jup_ and a mass of 0.30^+0.07^_-0.08_M_Jup_ in a 6.40 day orbit. Despite its high insolation flux (~600F_{Earth}_), TOI-622b does not show any evidence of radius inflation. TOI-2641b is a 0.39^+0.02^_-0.04_M_Jup_ planet in a 4.88 day orbit with a grazing transit (b=1.04^+0.05^_-0.06_) that results in a poorly constrained radius of 1.61^+0.46^_-0.64_R_Jup_. Additionally, TOI-615b is considered attractive for atmospheric studies via transmission spectroscopy with ground-based spectrographs and JWST. Future atmospheric and spin-orbit alignment observations are essential since they can provide information on the atmospheric composition, formation and migration of exoplanets across various stellar types.2023A&A...675A..39Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/675/A39CatalogResearchIsServedByTAP 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/675/A39https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/675/A39http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/675/A39https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/675/A39https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/675/A39http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/675/A39GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/675/A39/stars (Studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/675/A39/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/675/A39/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/675/A39/stars?GETtext/xml+votable180.050000true133.4087917-40.54381110.0055555555555555566/38248 39198 39255https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/675/A39?format=asciiOpticaldefaultJ/A+A/675/A39/starsStudied starsrecnoRecord number assigned by the VizieR team.
