Recent surveys have revealed that planets intermediate in size between Earth and Neptune (‘super-Earths’) are among the most common planets in the Galaxy. Atmospheric studies are the next step towards developing a comprehensive understanding of this new class of object. Much effort has been focused on using transmission spectroscopy to characterize the atmosphere of the super-Earth archetype GJ 1214b (refs 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17), but previous observations did not have… Expand
The transit spectra of Earth and Jupiter
Abstract In recent years, an increasing number of observations have been made of the transits of ‘Hot Jupiters’, such as HD 189733b, about their parent stars from the visible through to mid-infraredExpand
Water vapour in the atmosphere of the habitable-zone eight-Earth-mass planet K2-18 b
In the past decade, observations from space and the ground have found water to be the most abundant molecular species, after hydrogen, in the atmospheres of hot, gaseous extrasolar planets1–5. BeingExpand
Atmospheric reconnaissance of the habitable-zone Earth-sized planets orbiting TRAPPIST-1
Seven temperate Earth-sized exoplanets readily amenable for atmospheric studies transit the nearby ultracool dwarf star TRAPPIST-1 (refs 1,2). Their atmospheric regime is unknown and could range fromExpand
Hubble Space Telescope Near-IR Transmission Spectroscopy of the Super-Earth HD 97658b
Recent results from the Kepler mission indicate that super-Earths (planets with masses between 1 10 times that of the Earth) are the most common kind of planet around nearby Sun-like stars. TheseExpand
Ground-based transit observations of the super-Earth GJ 1214 b ⋆
Context. GJ 1214 b is one of the few known transiting super-Earth-sized exoplanets with a measured mass and radius. It orbits an Mdwarf, only 14.55 pc away, making it a favorable candidate forExpand
Variability in the super-Earth 55 Cnc e
Considerable progress has been made in recent years in observations of atmospheric signatures of giant exoplanets, but processes in rocky exoplanets remain largely unknown due to major challenges inExpand
A Search for Water in a Super-Earth Atmosphere: High-resolution Optical Spectroscopy of 55Cancri e
We present the analysis of high-resolution optical spectra of four transits of 55Cnc e, a low-density, super-Earth that orbits a nearby Sun-like star in under 18 hours. The inferred bulk density ofExpand
A combined transmission spectrum of the Earth-sized exoplanets TRAPPIST-1 b and c
TLDR
Observations of the combined transmission spectrum of the two inner planets during their simultaneous transits on 4 May 2016 rule out cloud-free hydrogen-dominated atmospheres for each planet at ≥10σ levels; TRAPPIST-1 b and c are therefore unlikely to have an extended gas envelope as they occupy a region of parameter space in which high-altitude cloud/haze formation is not expected to be significant for hydrogen- dominated atmospheres.

CLOUDS IN SUPER-EARTH ATMOSPHERES: CHEMICAL EQUILIBRIUM CALCULATIONS
Recent studies have unequivocally proven the existence of clouds in super-Earth atmospheres (Kreidberg et al. 2014). Here we provide a theoretical context for the formation of super-Earth clouds byExpand
A system of three transiting super-Earths in a cool dwarf star
We present the detection of three super-Earths transiting the cool star LP415-17, monitored by K2 mission in its 13th campaign. High resolution spectra obtained with HARPS-N/TNG showed that the starExpand

The newly discovered planet GJ 1214b is the first known transiting super-Earth requiring a significant atmosphere to explain its observed mass and radius. Models for the structure of this planetExpand
A ground-based transmission spectrum of the super-Earth exoplanet GJ 1214b
TLDR
A ground-based measurement of the transmission spectrum of GJ 1214b between wavelengths of 780 and 1,000 nm is reported, finding the lack of features in this spectrum rules out cloud-free atmospheres composed primarily of hydrogen. Expand
HIGH-RESOLUTION, DIFFERENTIAL, NEAR-INFRARED TRANSMISSION SPECTROSCOPY OF GJ 1214b
The nearby star GJ 1214 hosts a planet intermediate in radius and mass between Earth and Neptune, resulting in some uncertainty as to its nature. We have observed this planet, GJ 1214b, duringExpand
