cds-question@unistra.frmultiple-starsexoplanetsradial-velocityvisible-astronomyspectroscopyDiscovering and characterizing exoplanets at the outer edge of the transit method's sensitivity has proven challenging owing to geometric biases and the practical difficulties associated with acquiring long observational baselines. Nonetheless, a sample of giant exoplanets on orbits longer than 100 days has been identified by transit hunting missions. We present long-term Doppler spectroscopy for 11 such systems with observation baselines spanning a few years to a decade. We model these radial velocity observations jointly with transit photometry to provide initial characterizations of these objects and the systems in which they exist. Specifically, we make new precise mass measurements for four long-period giant exoplanets (Kepler-111c, Kepler-553c, Kepler-849b, and PH-2b), we place new upper limits on mass for four others (Kepler-421b, KOI-1431.01, Kepler-1513b, and Kepler-952b), and we show that several confirmed planets are in fact not planetary at all. We present these findings to complement similar efforts focused on closer-in short-period giant planets, and with the hope of inspiring future dedicated studies of cool giant exoplanets.2024ApJS..271...16Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/271/16CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/350 : Gaia EDR3 (Gaia Collaboration, 2020)J/ApJS/152/261 : Chromospheric CaII emission in nearby stars (Wright+, 2004)J/ApJ/725/875 : Chromospheric activity for CPS stars (Isaacson+, 2010)J/ApJ/784/45 : Kepler's multiple planet candidates.
