Our observations place a model dependent upper mass limit of 12-20 Jupiter masses from 4 to 10 AU, covering the semi-major axis search space between interferometric imaging measurements and other direct imaging non-detections. These observations rule out models where the large semi-major axis for the putative candidate companion Fomalhaut b is explained by dynamical scattering from a more massive companion in the inner stellar system, where such giant planets are thought to form.", "revisions": [ { "version": "v1", "updated": "2012-12-06T21:00:04.000Z" } ], "analyses": { "keywords": [ "solar system scales", "coronagraphic observations", "model dependent upper mass limit", "semi-major axis search space", "inner stellar system" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/0004-637X/764/1/7", "journal": "The Astrophysical Journal", "year": 2013, "month": "Feb", "volume": 764, "number": 1, "pages": 7 }, "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1206266, "adsabs": "2013ApJ...764....7K" } } }
