cds-question@unistra.frmultiple-starsexoplanetsphotometryGiant, wide-separation planets often lie in the gap between multiple, distinct rings of circumstellar debris: this is the case for the HR 8799 and HD 95086 systems, and even the Solar system where the Asteroid and Kuiper belts enclose the four gas and ice giants. In the case that a debris disc, inferred from an infrared excess in the SED, is best modelled as two distinct temperatures, we infer the presence of two spatially separated rings of debris. Giant planets may well exist between these two belts of debris, and indeed could be responsible for the formation of the gap between these belts. We observe 24 such two-belt systems using the VLT/SPHERE high-contrast imager, and interpret our results under the assumption that the gap is indeed formed by one or more giant planets. A theoretical minimum mass for each planet can then be calculated, based on the predicted dynamical time-scales to clear debris. The typical dynamical lower limit is ~0.2M_J_ in this work, and in some cases exceeds 1M_J_. Direct imaging data, meanwhile, are typically sensitive to planets down to ~3.6M_J_ at 1 arcsec, and 1.7M_J_ in the best case. Together, these two limits tightly constrain the possible planetary systems present around each target, many of which will be detectable with the next generation of high-contrast imagers.2018MNRAS.480.2757Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/480/2757CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/480/2757https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/480/2757http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/480/2757https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/480/2757https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/480/2757http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/480/2757GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/480/2757/list (List of survey stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/480/2757/list?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/480/2757/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/480/2757/list?GETtext/xml+votable180.050000true126.6050417-52.80750.0055555555555555566/4115 12467 16543 32087 37810 41352 42047 42424 42684 42711 42758 42911 43232 43292 43298 43358 43369 43372 44044 44146https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/480/2757?format=asciidefaultJ/MNRAS/480/2757/listList of survey starsSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
