cds-question@unistra.frk-starsradial-velocityapparent-magnitudeastrometryephemeridesWe have used high-cadence radial velocity measurements from the Hobby-Eberly Telescope with published velocities from the Lick 3 m Shane Telescope, combined with astrometric data from the Hubble Space Telescope (HST) Fine Guidance Sensors to refine the orbital parameters of the HD 128311 system, and determine an inclination of 55.95{deg}+/-14.55{deg} and true mass of 3.789_-0.432_^+0.924^ M_JUP_ for HD 128311 c. The combined radial velocity data also reveal a short period signal which could indicate a third planet in the system with an Msin i of 0.133+/-0.005 M_JUP_or stellar phenomena. Photometry from the T12 0.8 m automatic photometric telescope at the Fairborn Observatory and HST are used to determine a photometric period close to, but not within the errors of the radial velocity signal. We performed a cross-correlation bisector analysis of the radial velocity data to look for correlations with the photometric period and found none. Dynamical integrations of the proposed system show long-term stability with the new orbital parameters of over 10 million years. Our new orbital elements do not support the claims of HD 128311 b and c being in mean motion resonance.2014ApJ...795...41Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/795/41CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/47 : Stellar Radial Velocities 0-20 hrs (Evans 1967)I/255 : The HST Guide Star Catalog, Version GSC-ACT (Lasker+ 1996-99)J/A+A/596/A116 : Radial velocities of K-M dwarfs (Sperauskas+, 2016)J/ApJ/715/1203 : {upsilon} Andromedae system with HST (McArthur+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/795/41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/795/41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/795/41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/795/41https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/795/41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/795/41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/795/41/table7 (HST Astrometric Data for HD128311)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/795/41/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/795/41/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/795/41/table7?GETtext/xml+votable180.050000true219.026049.724110.0055555555555555566/8357 16212 16213 42248 42249https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/795/41?format=asciiOpticaldefaultJ/ApJ/795/41/table4HET Relative Radial Velocities for HD128311recnoRecord number assigned by the VizieR team.
