Rocky planets are common around other stars, but their atmospheric properties remain
largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming …

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

There are no planets intermediate in size between Earth and Neptune in our Solar System,
yet these objects are found around a substantial fraction of other stars. Population statistics …

With no analogues in the Solar System, the discovery of thousands of exoplanets with
masses and radii intermediate between Earth and Neptune was one of the big surprises of …

Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …

The search for rocky planet atmospheres with JWST has focused on planets transiting M
dwarfs. Such planets have favorable planet-to-star size ratios, enhancing the amplitude of …

The near-infrared transmission spectrum of the warm sub-Neptune exoplanet GJ 1214 b has
been observed to be flat and featureless, implying a high metallicity atmosphere with …

Aerosols have been found to be nearly ubiquitous in substellar atmospheres,–. The precise
temperature at which these aerosols begin to form in exoplanets has yet to be …

We present the discovery and characterisation of two transiting planets observed by the
Transiting Exoplanet Survey Satellite (TESS) orbiting the nearby (d⋆≈ 22 pc), bright (J≈ 9 …

A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance
among the first and most accessible planetary layers observed from space, it is closely …
