BREEDING SUPER-EARTHS AND BIRTHING SUPER-PUFFS IN TRANSITIONAL DISKS (2015, background): “Super-puffs are the exception, not the rule: planets with R > 4R⊕ are more than an order-of-magnitude more rare at orbital periods < 50 days than planets with R < 4R⊕ (Fressin et al. 2013).10 Examples include Kepler-51b (Steffen et al. 2013), a 2.1+1.5−0.8M⊕ planet of size 7.1±0.3R⊕ orbiting its hos”

ECCENTRICITY FROM TRANSIT PHOTOMETRY: SMALL PLANETS IN KEPLER MULTI-PLANET SYSTEMS HAVE LOW ECCENTRICITIES (2015, background): “Kepler-56 (KOI-1241) contains two transiting planets with mutual TTVs (Steffen et al. 2013).”
VALIDATION OF KEPLER'S MULTIPLE PLANET CANDIDATES. II. REFINED STATISTICAL FRAMEWORK AND DESCRIPTIONS OF SYSTEMS OF SPECIAL INTEREST (2014, background): “If the simulated TTVs do not clearly exceed the observed TTVs, we perform another fit to the transit times, letting the mass of the giant float, and we measure the change in χ2 per degree of freedom (dof).”
FALSE POSITIVE PROBABILITIES FOR ALL KEPLER OBJECTS OF INTEREST: 1284 NEWLY VALIDATED PLANETS AND 428 LIKELY FALSE POSITIVES (2016, background): “…Pasadena, CA 91125, USA 7 Hubble Fellow ing variations (TTVs) in multi-planet systems (e.g., Ford et al. 2012; Steffen et al. 2012; Fabrycky et al. 2012; Steffen et al. 2013; Jontof-Hutter et al. 2015), but this still leaves the vast majority of candidates inaccessible to dynamical confirmation.”
