cds-question@unistra.frmultiple-starsexoplanetsradial-velocityvisible-astronomyWe report the discovery and characterisation of three transiting warm Jupiters: TIC 147027702b, TIC 245076932b and TIC 87422071b. These systems were initially identified as transiting candidates using light curves generated from the full-frame images of the TESS mission. We confirmed the planetary nature of these objects with ground-based spectroscopic follow-up observations using FEROS and the new PLATOSpec spectrograph attached to the ESO 1.52m telescope at the La Silla Observatory, and with ground-based photometric observations of the Observatoire Moana, Las Cumbres Observatory Global Telescope and ASTEP. From a global fit to the photometry and radial velocities, we determine that the planet TIC 147027702b has a low-eccentric orbit (e=0.13+/-0.05) with a period of 44.4 days and has a mass of 1.09^+0.07^_-0.13_M_J_ and a radius of 0.98+/-0.06R_J_. TIC 245076932b has a moderately low mass of 0.51+/-0.05M_J_, a radius of 0.97+/-0.05R_J_, and an eccentric orbit (e=0.43+/-0.02) with a period of 21.6 days. TIC 87422071b has a mass of 1.29+/-0.10M_J_, a radius of 0.97+/-0.08R_J_, and has a slightly eccentric orbit (e=0.12+/-0.07) with a period of 11.3 days. These well-characterised warm Jupiters expand the currently limited sample of similar gas giants and provide valuable benchmarks for testing models of giant-planet formation, migration, and tidal evolution.2026A&A...708A.189Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/708/A189CatalogResearchIsServedByTAP VizieR generic 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/708/A189https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/708/A189http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/708/A189https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/708/A189https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/708/A189http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/708/A189GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/708/A189/tic147Radial-velocity data of TIC 147027702recnoRecord number assigned by the VizieR team.
