Planetary Candidates Observed by Kepler IV: Planet Sample From Q1-Q8 (22 Months)
Christopher J. Burke, Stephen T. Bryson, F. Mullally +37
We provide updates to the Kepler planet candidate sample based upon nearly two years of high-precision photometry (i.e., Q1-Q8). From an initial list of nearly 13,400 Threshold Cro…
KOI-2700b - A Planet Candidate With Dusty Effluents on a 22-Hour Orbit
S. Rappaport, T. Barclay, J. DeVore +3
Kepler planet candidate KOI-2700b (KIC 8639908b) with an orbital period of 21.84 hours exhibits a distinctly asymmetric transit profile, likely indicative of the emission of dusty…
Utilitarian Opacity Model for Aggregate Particles in Protoplanetary Nebulae and Exoplanet Atmospheres
Jeffrey N. Cuzzi, Paul R. Estrada, Sanford S. Davis
As small solid grains grow into larger ones in protoplanetary nebulae, or in the cloudy atmospheres of exoplanets, they generally form porous aggregates rather than solid spheres.…
Revised Stellar Properties of Kepler Targets for the Quarter 1-16 Transit Detection Run
Daniel Huber, Victor Silva Aguirre, Jaymie M. Matthews +19
We present revised properties for 196,468 stars observed by the NASA Kepler Mission and used in the analysis of Quarter 1-16 (Q1-Q16) data to detect and characterize transiting exo…
Three-Dimensional Radiation-Hydrodynamics Calculations of the Envelopes of Young Planets Embedded in Protoplanetary Disks
Gennaro D'Angelo, Peter Bodenheimer
We perform global three-dimensional (3D) radiation-hydrodynamics calculations of the envelopes surrounding young planetary cores of 5, 10, and 15 Earth masses, located in a protopl…
Characterizing the purple Earth: Modelling the globally-integrated spectral variability of the Archean Earth
E. Sanromá, E. Pallé, M. N. Parenteau +4
The ongoing searches for exoplanetary systems have revealed a wealth of planets with diverse physical properties. Planets even smaller than the Earth have already been detected, an…
