cds-question@unistra.frradial-velocityphotometryHigh-precision, high-cadence radial velocity monitoring over the past 8yr at the W. M. Keck Observatory reveals evidence for a third planet orbiting the nearby (4.69pc) dM4 star GJ 876. The residuals of three-body Newtonian fits, which include GJ 876 and Jupiter-mass companions b and c, show significant power at a periodicity of 1.9379days. Self-consistently fitting the radial velocity data with a model that includes an additional body with this period significantly improves the quality of the fit.2005ApJ...634..625Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/634/625CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/634/625https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/634/625http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/634/625https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/634/625https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/634/625http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/634/625GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/634/625/table5Photometric observations of GJ 876recnoRecord number assigned by the VizieR team.
