Giant Outer Transiting Exoplanet Mass survey. IV.

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.
