Exoplanets with substantial hydrogen/helium atmospheres have been discovered in
abundance, many residing extremely close to their parent stars. The extreme irradiation …

The inception of plate tectonics on Earth and its subsequent evolution are discussed on the
basis of theoretical considerations and observational constraints. The likelihood of plate …

Context. ESPRESSO is the new high-resolution spectrograph of ESO's Very Large
Telescope (VLT). It was designed for ultra-high radial-velocity (RV) precision and extreme …

The population of small, close-in exoplanets is bifurcated into super-Earths and sub-
Neptunes. We calculate physically motivated mass–radius relations for sub-Neptunes, with …

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 …

Abstract NASA's Kepler Space Telescope was designed to determine the frequency of Earth-
sized planets orbiting Sun-like stars, but these planets are on the very edge of the mission's …

Various theoretical models treating the effect of stellar irradiation on planetary envelopes
predict the presence of a radius valley, ie a bimodal distribution of planet radii, with super …

I introduce batman, a Python package for modeling exoplanet transit and eclipse light
curves. The batman package supports calculation of light curves for any radially symmetric …

Abstract The Kepler Mission was designed to identify and characterize transiting planets in
the Kepler Field of View and to determine their occurrence rates. Emphasis was placed on …

We present an improved estimate of the occurrence rate of small planets orbiting small stars
by searching the full four-year Kepler data set for transiting planets using our own planet …
