cds-question@unistra.frvariable-starsradial-velocityvisible-astronomymedium-band-photometrysolar-system-planetsmultiple-starsAs part of the Transit Ephemeris Refinement and Monitoring Survey, we present new radial velocities and photometry of the HD 192263 system. Our analysis of the already available Keck-HIRES and CORALIE radial velocity measurements together with the five new Keck measurements we report in this paper results in improved orbital parameters for the system. We derive constraints on the size and phase location of the transit window for HD 192263b, a Jupiter-mass planet with a period of 24.3587+/-0.0022 days. We use 10 years of Automated Photoelectric Telescope photometry to analyze the stellar variability and search for planetary transits. We find continuing evidence of spot activity with periods near 23.4 days. The shape of the corresponding photometric variations changes over time, giving rise to not one but several Fourier peaks near this value. However, none of these frequencies coincides with the planet's orbital period and thus we find no evidence of star-planet interactions in the system. We attribute the ~23 day variability to stellar rotation. There are also indications of spot variations on longer (8 years) timescales. Finally, we use the photometric data to exclude transits for a planet with the predicted radius of 1.09R_J_, and as small as 0.79R_J_.2012ApJ...754...37Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/754/37CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/552/A119 : Planet-star and moon-planet interaction (Saur+, 2013)J/A+A/552/A27 : Stellar activity and kinematics of FGK stars (Murgas+, 2013)J/ApJ/745/24 : A search for new companions with CHARA (Raghavan+, 2012)J/ApJ/733/68 : Exoplanet masses derived from RVs (Brown+, 2011)J/ApJS/190/1 : A survey of stellar families (Raghavan+, 2010)J/ApJ/716/1336 : Stability analysis of single-planet (Kopparapu+, 2010)J/A+A/521/A40 : Stroemgren photometry of Milky Way stars (Arnadottir+, 2010)J/A+A/521/A12 : Radial velocities of nearby late-type stars (Maldonado+, 2010)J/ApJ/705/1226 : Planet-bearing stars in Spitzer (Bryden+, 2009)J/ApJ/694/1085 : Radii of exoplanet host stars (van Belle+, 2009)J/ApJ/666/475 : Extrasolar planet taxonomy (Marchi+, 2007)J/ApJ/649/1010 : Habitability of known exoplanetary systems (Jones+, 2006)J/ApJ/646/505 : Catalog of nearby exoplanets (Butler+, 2006)J/ApJ/646/523 : Exoplanet systems with stellar companions (Raghavan+, 2006)J/ApJ/622/1102 : The planet-metallicity correlation.
