cds-question@unistra.frmultiple-starsexoplanetsradial-velocityvisible-astronomyHot and warm Jupiters might have undergone the same formation and evolution path, but the two populations exhibit different distributions of orbital parameters, challenging our understanding on their actual origin. The present work, which is the results of our warm Jupiters survey carried out with the CHIRON spectrograph within the KESPRINT collaboration, aims to address this challenge by studying two planets that could help bridge the gap between the two populations. We report the confirmation and mass determination of a hot Jupiter (orbital period shorter than 10 days), TOI-2420 b, and a warm Jupiter, TOI-2485 b. We performed a joint analysis using a wide variety of spectral and photometric data in order to characterize these planetary systems. We found that TOI-2420 b has an orbital period of P_b_=5.8 days, a mass of M_b_=0.9M_J_ and a radius of R_b_=1.3R_J_, with a planetary density of 0.477g/cm^3^; while TOI-2485 b has an orbital period of P_b_=11.2 days, a mass of M_b_=2.4M_J_ and a radius of R_b_=1.1R_J_ with density 2.36g/cm^3^. With current parameters, the migration history for TOI-2420 b and TOI-2485 b is unclear: the high-eccentricity migration scenarios cannot be ruled out, and TOI-2485 b's characteristics may rather support this scenario.2024A&A...690A..18Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/690/A18CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/690/A18https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/690/A18http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/690/A18https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/690/A18https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/690/A18http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/690/A18GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/690/A18/toi-2420Radial velocities acquired for TOI-2420RVRadial velocity or relative radial velocity for TRES data of TOI-2485km/sphys.veloc;pos.heliocentricdoublee_RVRadial velocity uncertaintykm/sstat.errordoubleInstName of the Instrumentmeta.id;instrcharrecnoRecord number assigned by the VizieR team.
