We provide a brief review of many aspects of the planetary physics of hot Jupiters. Our aim is
to cover most of the major areas of current study while providing the reader with additional …

The field of exoplanet atmospheric characterization has recently made considerable
advances with the advent of high-resolution spectroscopy from large ground-based …

The extreme ultraviolet (EUV)/X-ray photoevaporation and core-powered mass-loss models
are both capable of reproducing the bimodality in the sizes of small, close-in exoplanets …

Transit surveys indicate that there is a deficit of Neptune-sized planets on close-in orbits. If
this" Neptune desert" is entirely cleared out by atmospheric mass loss, then planets at its …

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 …

The distribution of close-in exoplanets is shaped by a complex interplay between
atmospheric and dynamical processes. The Desert-Rim Exoplanets Atmosphere and …

We present the detection of neutral helium at 10833 Å in the atmosphere of WASP-52b and
tentative evidence of helium in the atmosphere of the grazing WASP-177b, using high …

High resolution transit spectroscopy has proven to be a reliable technique for the
characterization of the chemical composition of exoplanet atmospheres. Taking advantage …

The warm Neptune GJ 3470b transits a nearby (d= 29 pc) bright slowly rotating M1. 5-dwarf
star. Using spectroscopic observations during two transits with the newly commissioned …

The metastable helium triplet in the near-infrared (10 833 Å) is among the most important
probes of exoplanet atmospheres. It can trace their extended outer layers and constrain …
