{ "description": "<p>Well-characterized multiplanetary systems offer a unique opportunity for comparative planetology, allowing for investigations of the formation and evolution processes. I will present the analysis of a new multiplanetary system, TOI-561, initially discovered by the TESS mission through photometric observations, and further characterized using high-precision RV data collected with the HARPS-N spectrograph, that allowed us to obtain precise masses for all the four planets in the system, namely an ultra-short period super-Earth and three mini-Neptunes (Lacedelli et al. 2021). I will show how in this case combining photometric and RV data has been essential to discriminate between various possible architectures, highlighting the importance of combining different techniques to obtain a better characterization of a planetary system. Additional insights on the planetary architecture and internal structure are coming from the ultra-high precision photometry of the CHEOPS satellite (Lacedelli et al., in prep), which additionally stresses the importance of synergies between various techniques and instruments.</p>", "license": "https://creativecommons.org/licenses/by/4.0/legalcode", "creator": [ { "affiliation": "Universit\u00e0 degli Studi di Padova, INAF-OAPD", "@id": "https://orcid.org/0000-0002-4197-7374", "@type": "Person", "name": "Lacedelli Gaia" }, { "affiliation": "Universit\u00e0 degli Studi di Padova, INAF-OAPD", "@id": "https://orcid.org/0000-0002-6492-2085", "@type": "Person", "name": "Malavolta Luca" }, { "affiliation": "INAF-OAPD", "@id": "https://orcid.org/0000-0003-0066-9268", "@type": "Person", "name": "Borsato Luca" }, { "affiliation": "Universit\u00e0 degli Studi di Padova, INAF-OAPD", "@id": "https://orcid.org/0000-0002-9937-6387", "@type": "Person", "name": "Piotto Giampaolo" }, { "affiliation": "Laboratoire d'Astrophysique de Marseille", "@id": "https://orcid.org/0000-0003-1149-3659", "@type": "Person", "name": "Nardiello Domenico" }, { "@type": "Person", "name": "the HARPS-N team" }, { "@type": "Person", "name": "the CHEOPS team" } ], "sameAs": [ "https://doi.org/10.5281/zenodo.5123553" ], "datePublished": "2021-10-10", "url": "https://zenodo.org/record/5559862", "@type": "CreativeWork", "keywords": [ "Exoplanets", "Exoplanets Detection And Characterization", "Transits", "Radial Velocity", "TOI-561" ], "@context": "https://schema.org/", "identifier": "https://doi.org/10.5281/zenodo.5559862", "@id": "https://doi.org/10.5281/zenodo.5559862", "workFeatured": { "@type": "Event", "name": "PLATO Mission Conference 2021" }, "name": "CHEOPS, HARPS-N and TESS: a joint effort to characterize the unexpected planetary system around TOI-561" }
