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

The search for habitable environments and biomarkers in exoplanetary atmospheres is the
holy grail of exoplanet science. The detection of atmospheric signatures of habitable Earth …

The JWST has ushered in a new era in atmospheric characterisations of temperate low-
mass exoplanets with recent detections of carbon-bearing molecules in the candidate …

Over the last decade, precise exoplanet transmission spectroscopy has revealed the
atmospheres of dozens of exoplanets, driven largely by observatories like the Hubble Space …

Recent work on the characterization of small exoplanets has allowed us to accumulate
growing evidence that sub-Neptunes with radii greater than∼ 2.5 R⊕ often host H 2/He …

We present an in-depth, high-resolution spectroscopic analysis of the M dwarf K2-18, which
hosts a sub-Neptune exoplanet in its habitable zone. We show our technique to accurately …

Laboratory spectroscopic data is essential for the modeling of hot exoplanet atmospheres,
since molecules such as methane, a major component of hot-Jupiter-type exoplanet …

The study of temperate sub-Neptunes is the new frontier in exoplanetary science. A major
development in the past year has been the first detection of carbon-bearing molecules in the …

Context. The atmospheric characterisation of hot and warm Neptune-size exoplanets is
challenging mainly due to their relatively small radius and atmospheric scale height, which …

The cross-correlation function and template matching techniques have dominated the world
of precision radial velocities for many years. Recently, a new technique, named line-by-line …
