THE KEPLER-19 SYSTEM: A TRANSITING 2.2<i>R</i><sub>⊕</sub>PLANET AND A SECOND PLANET DETECTED VIA TRANSIT TIMING VARIATIONS
We present the discovery of the Kepler-19 planetary system, which we first identified from a 9.3 day periodic transit signal in the Kepler photometry. From high-resolution spectroscopy of the star, we find a stellar effective temperature Teff = 5541 ± 60 K, a metallicity [Fe/H] = −0.13 ± 0.06, and …
