cds-question@unistra.frmultiple-starsexoplanetsradial-velocityphotometryvisible-astronomyHot Jupiters are key targets for understanding planet formation, migration and atmospheres. Yet, most of the ground-based observational resources for the follow-up of the TESS mission are focused on the confirmation of low-mass planet candidates. This leaves the more massive planets, such as hot Jupiters, without mass determinations and definitive confirmations. We use the CAFE_2_ spectrograph at the Calar Alto Observatory to monitor the radial velocity of stars with hot-Jupiter candidates that have been left behind by follow-up efforts with the goal of confirming their planetary nature. Here, we present the results for seven candidates. We monitor the radial velocity of the seven candidate host stars TOI-603, TOI-1137, TOI-1837, TOI-2114, TOI-4492, TOI-5806, and TOI-5811. Each hosts a hot-Jupiter candidate detected by the TESS mission. We characterize these stars and jointly model the CAFE radial velocities and the TESS photometric data to unravel the nature of the transiting objects and to infer their properties. The objects confirmed to be new planets are TOI-603 b (mass 33.0^+6.5^_-6.2_M_{Earth}_, period 16.2d), TOI-2114 b (1.01^+0.146^_-0.12_M_{jup}_, 6.2 d), TOI-4492 b (5.92^+0.67^_-0.64_M_{jup}_, 4.4d), TOI-5806 b (2.77^+0.34^_-0.32_M_{jup}_, 3.2d), and TOI-5811 B b (0.81^+0.11^_-0.10_M_{jup}_, 6.3d). Based on their masses and periods, TOI-603 b is a member of the "Neptune savanna", while TOI-2114 b, TOI-4492 b, TOI-5806 b, and TOI-5811 B b are hot Jupiters orbiting slightly evolved stars. We found the candidate TOI-5811.01 to actually be a planet but orbiting the nearby bound companion TOI-5811 B. We also identify a bound stellar companion to TOI-5806 at a projected separation of 248 au, thus both forming S-type (satellite-type) planetary systems. As for the other two candidates, TOI-1837.01 is definitely an eclipsing binary, while the nature of TOI-1137.01 remains indeterminate. The five newly confirmed planets orbit relatively bright stars (G=8.6-10.2mag) and four of them are excellent candidates for atmospheric studies (with transmission spectroscopy metrics exceeding 90 for TOI-603 b, TOI-2114 b, TOI-5806 b, and TOI-5811 B b). The complex configurations of all these systems underscore the need for intensive follow-up efforts to clarify the nature of transiting planet candidates.2026A&A...713A.272Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/713/A272CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/713/A272https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/713/A272http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/713/A272https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/713/A272https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/713/A272http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/713/A272GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/713/A272/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/713/A272/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/713/A272/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/713/A272/stars?GETtext/xml+votable180.050000true301.177666730.40988890.0055555555555555566/4161 9477 10364 12652 12891 13198 14428https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/713/A272?format=asciiOpticaldefaultJ/A+A/713/A272/starsList of studied starsrecnoRecord number assigned by the VizieR team.
