cds-question@unistra.frmultiple-starsexoplanetsphotometryvisible-astronomyAmong the thousands of exoplanets discovered to date, approximately a few hundred gas giants on short-period orbits are classified as "lonely" and only a few are in a multi-planet system with a smaller companion on a close orbit. The processes that formed multi-planet systems hosting gas giants on close orbits are poorly understood, and only a few examples of this kind of system have been observed and well characterised. Within the contest of multi-planet system hosting gas-giant on short orbits, we characterise TOI-1130 system by measuring masses and orbital parameters. This is a 2-transiting planet system with a Jupiter-like planet (c) on a 8.35 days orbit and a Neptune-like planet (b) on an inner (4.07 days) orbit. Both planets show strong anti-correlated transit timing variations (TTVs). Furthermore, radial velocity (RV) analysis showed an additional linear trend, a possible hint of a non-transiting candidate planet on a far outer orbit. Since 2019, extensive transit and radial velocity observations of the TOI-1130 have been acquired using TESS and various ground-based facilities. We present a new photo-dynamical analysis of all available transit and RV data, with the addition of new CHEOPS and ASTEP+ data that achieve the best precision to date on the planetary radii and masses and on the timings of each transit. We were able to model interior structure of planet b constraining the presence of a gaseous envelope of H/He, while it was not possible to assess the possible water content. Furthermore, we analysed the resonant state of the two transiting planets, and we found that they lie just outside the resonant region. This could be the result of the tidal evolution that the system underwent. We obtained both masses of the planets with a precision less than 1.5%, and radii with a precision of about 1% and 3% for planet b and c, respectively.2024A&A...689A..52Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/689/A52CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/675/A115 : TOI-1130 radial velocities (Korth+, 2023)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/689/A52https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/689/A52http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/689/A52https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/689/A52https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/689/A52http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/689/A52GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/689/A52/tablee1TOI-1130 b transit timesrecnoRecord number assigned by the VizieR team.
