Visual Analysis and Demographics of Kepler Transit Timing Variations
Mackenzie Kane, Darin Ragozzine, Xzavier Flowers +3
We visually analyzed the Transit Timing Variation (TTV) data of 5930 Kepler Objects of Interest (KOIs) homogeneously. Using data from Rowe et al. 2014 and Holczer et al. 2016, we i…
Transit Timing Observations from Kepler. IX. Catalog of the Full Long-Cadence Data Set
Tomer Holczer, Tsevi Mazeh, Gil Nachmani +6
We present a new transit timing catalog of 2599 Kepler Objects of Interest (=KOIs), using the PDC-MAP long-cadence light curves that include the full seventeen quarters of the miss…
Dearth of short-period Neptunian exoplanets - a desert in period-mass and period-radius planes
Tsevi Mazeh, Tomer Holczer, Simchon Faigler
A few studies have reported a significant dearth of exoplanets with Neptune mass and radius with orbital periods below -- d. This cannot be explained by observational biases…
Secure TTV Mass Measurements: Ten Kepler Exoplanets between 3 and 8 Earth Masses with Diverse Densities and Incident Fluxes
Daniel Jontof-Hutter, Eric B. Ford, Jason F. Rowe +7
We infer dynamical masses in eight multi-planet systems using transit times measured from Kepler's complete dataset, including short-cadence data where available. Of the eighteen d…
Kepler423b: a half-Jupiter mass planet transiting a very old solar-like star
D. Gandolfi, H. Parviainen, H. J. Deeg +16
We report the spectroscopic confirmation of the Kepler object of interest KOI-183.01 (Kepler-423b), a half-Jupiter mass planet transiting an old solar-like star every 2.7 days. Our…
Transit Timing Observations from Kepler. VIII Catalog of Transit Timing Measurements of the First Twelve Quarters
Tsevi Mazeh, Gil Nachmani, Tomer Holczer +13
Following Ford et al. (2011, 2012) and Steffen et al. (2012) we derived the transit timing of 1960 Kepler KOIs using the pre-search data conditioning (PDC) light curves of the firs…
