cds-question@unistra.frmultiple-starsexoplanetsradial-velocityvisible-astronomyWhile several thousand exoplanets are now confirmed, the number of known transiting warm Jupiters (10d < period < 200d) remains relatively small. These planets are generally believed to have formed outside the snowline and migrated to their current orbits. Because they are sufficiently distant from their host stars, they mitigate proximity effects and so offer valuable insights into planet formation and evolution. Here, we present the study of seven systems, three of which - TOI-2295, TOI-2537, and TOI-5110 - are newly discovered planetary systems. Through the analysis of TESS photometry, SOPHIE radial velocities (RVs), and high-spatial resolution imaging, we found that TOI-2295b, TOI-2537b, and TOI-5110b are transiting warm Jupiters with orbital periods ranging from 30 to 94d, masses between 0.9 and 2.9MJ, and radii ranging from 1.0 to 1.5RJ. Both TOI-2295 and TOI-2537 harbor at least one additional, outer planet. Their outer planets - TOI-2295c and TOI-2537c - are characterized by orbital periods of 966.5_-4.2_^+4.3^ and 1920_-140_^+230^d, respectively, and minimum masses of 5.61_-0.24_^+0.23^ and 7.23_-0.45_^+0.52^MJ, respectively. We have also investigated and characterized the two recently reported warm Jupiters TOI-1836b and TOI-5076b, which we independently detected in SOPHIE RVs. Our new data allow for further discussion of their nature and refinement of their parameters. Additionally, we study the planetary candidates TOI-4081.01 and TOI-4168.01. For TOI-4081.01, despite our detection in RVs, we cannot rule out perturbation by a blended eclipsing binary, and we thus exercise caution regarding its planetary nature. On the other hand, we identify TOI-4168.01 as a firm false positive; its RV curve exhibits a large amplitude in an antiphase relation with the transit ephemeris observed by TESS, indicating that the detected event is the eclipse of a secondary star rather than a planetary transit. Finally, we highlight interesting characteristics of these new planetary systems. The transits of TOI-2295b are highly grazing, with an impact parameter of 1.056_-0.043_^+0.063^. This leaves its radius uncertain but potentially makes it an interesting probe of gravitational dynamics in its two-planet system, as transit shapes for grazing planets are highly sensitive to even small variations in inclination. TOI-2537b, in turn, is a temperate Jupiter with an effective temperature of 307+/-15K and can serve as a valuable low-irradiation control for models of hot Jupiter inflation anomalies. We also detected significant transit timing variations (TTVs) for TOI-2537b, which are likely caused by gravitational interactions with the outer planet TOI-2537c. Further transit observations are needed to refine the analysis of these TTVs and enhance our understanding of the system's dynamics. Finally, TOI-5110b stands out due to its orbital eccentricity of 0.745_-0.027_^+0.030^, one of the highest planetary eccentricities discovered thus far. We find no conclusive evidence for an external companion, but an unseen planet with a semi-amplitude smaller than 10m/s could nonetheless still be exciting its eccentricity.2025A&A...694A..36Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/694/A36CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/694/A36https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/694/A36http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/694/A36https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/694/A36https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/694/A36http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/694/A36GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/694/A36/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/694/A36/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/694/A36/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/694/A36/stars?GETtext/xml+votable180.050000true245.908208354.689750.0055555555555555566/87 396 3646 8029 10151 15235 24440https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/694/A36?format=asciiOpticaldefaultJ/A+A/694/A36/starsList of studied starsProtRotational period (this work)dtime.periodinte_Prot?
