cds-question@unistra.frmultiple-starsexoplanetsccd-photometryvisible-astronomyHot Jupiters have been perceived as loners devoid of planetary companions in close orbital proximity. However, recent discoveries based on space-borne precise photometry have revealed that at least some fraction of giant planets coexists with low-mass planets in compact orbital architectures. We report detecting a 1.446-d transit-like signal in the photometric time series acquired with the Transiting Exoplanet Survey Satellite (TESS) for the WASP-84 system, which is known to contain a hot Jupiter on a circular 8.5-d orbit. The planet was validated based on TESS photometry, and its signal was distilled in radial velocity measurements. The joint analysis of photometric and Doppler data resulted in a multiplanetary model of the system. With a mass of 15M_{sun}_, radius of 2R_{sun}_, and orbital distance of 0.024au, the new planet WASP-84 c was classified as a hot super-Earth with the equilibrium temperature of 1300K. A growing number of companions to hot Jupiters indicates that a non-negligible part of them must have formed under a quiescent scenario such as disc migration or in situ formation.2023MNRAS.525L..43Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/525/L43CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/445/1114 : Transiting planetary system WASP-84 (Anderson+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/525/L43https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/525/L43http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/525/L43https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/525/L43https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/525/L43http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/525/L43GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/525/L43/lcNew ground-based transit light curvesrecnoRecord number assigned by the VizieR team.
