KEPLER PLANETS: A TALE OF EVAPORATION
Inspired by the Kepler mission's planet discoveries, we consider the thermal contraction of planets close to their parent star, under the influence of evaporation. The mass-loss rates are based onExpand
The evaporation valley in the Kepler planets
A new piece of evidence supporting the photoevaporation-driven evolution model for low-mass, close-in exoplanets was recently presented by the California-Kepler-Survey. The radius distribution of theExpand
EXTRACTING PLANET MASS AND ECCENTRICITY FROM TTV DATA
Most planet pairs in the Kepler data that have measured transit time variations (TTVs) are near first-order mean-motion resonances. We derive analytical formulae for their TTV signals. We separateExpand
DENSITY AND ECCENTRICITY OF KEPLER PLANETS
We analyze the transit timing variations (TTV) obtained by the Kepler mission for 22 sub-Jovian planet pairs (19 published, 3 new) that lie close to mean motion resonances. We find that the TTVExpand
Spacing of Kepler Planets: Sculpting by Dynamical Instability
We study the orbital architecture of multi-planet systems detected by the Kepler transit mission using N-body simulations, focusing on the orbital spacing between adjacent planets in systems showingExpand
Atmospheres of low-mass planets: the "boil-off"
We show that, for a low-mass planet that orbits its host star within a few tenths of an AU (like the majority of the {\it Kepler} planets), the atmosphere it was able to accumulate while embedded inExpand
Outer edges of debris discs - How sharp is sharp?
Context. Rings or annulus-like features have been observed in most imaged debris discs. Outside the main ring, while some systems (e.g., ! Pictoris and AU Mic) exhibit smooth surface brightnessExpand
SECULAR CHAOS AND THE PRODUCTION OF HOT JUPITERS
In a planetary system with two or more well-spaced, eccentric, inclined planets, secular interactions may lead to chaos. The innermost planet may gradually become very eccentric and/or inclined as aExpand
HOT JUPITERS IN BINARY STAR SYSTEMS
Radial velocity surveys find Jupiter-mass planets with semimajor axes a less than 0.1 AU around ~1% of solar-type stars; counting planets with a as large as 5 AU, the fraction of stars having planetsExpand
About 30% of Sun-like Stars Have Kepler-like Planetary Systems: A Study of their Intrinsic Architecture
We constrain the intrinsic architecture of Kepler planetary systems by modeling the observed multiplicities of the transiting planets (tranets) and their transit timing variations (TTVs). We robustlyExpand
