High Accuracy Molecular Line Lists for Studies of Exoplanets and Other Hot Atmospheres
Frontiers in Astronomy and Space Sciences, 2022 The desire to characterize and model the atmospheres of the many extrasolar planets that have been discovered over the last three decades is a major driver of current astronomy.

The Fourier-Kelvin Stellar Interferometer: a low-complexity low-cost space mission for high-resolution astronomy and direct exoplanet detection [PDF]
SPIE Proceedings, 2006 The Fourier-Kelvin Stellar Interferometer (FKSI) is a mission concept for a spacecraft-borne nulling interferometer for high-resolution astronomy and the direct detection of exoplanets and assay of their environments and atmospheres. FKSI is a high angular resolution system operating in the near to midinfrared spectral region and is a scientific and ...

Predicting Nitrogen Isotope Fractionation in Nitrate Deposition on Early Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Noachian and early Hesperian Mars were likely warm and wet, with an atmosphere abundant in molecular nitrogen. The recent discovery of nitrate deposits in the Yellowknife Bay mudstones at Gale Crater confirm the existence of nitrogen oxides (NOX) on Noachian Mars. The processes responsible for the production of these nitrates would fractionate

The Astronomical JournalWe examine the detectability of water (H _2 O) in the reflected-light spectrum of an Earth-like exoplanet assuming a photometric observational approach rather than spectroscopic. By quantifying the detectability as a function of normalized exposure time,

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer
Radio Science, Volume 61, Issue 6, June 2026.Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Individual and Statistical Characterization of the Giant Exoplanet Population
, 2021 The field of observational exoplanet astronomy has seen tremendous progress over the span of only a few decades. Now, we find ourselves at the dawn of a new era: the characterization of distant worlds.

A survey of exoplanet phase curves with Ariel [PDF]
, 2021 The ESA-Ariel mission will include a tier dedicated to exoplanet phase curves corresponding to ∼ 10 % of the science time. We present here the current observing strategy for studying exoplanet phase curves with Ariel.

The HD 191939 Exoplanet System is Well Aligned and Flat
The Astronomical JournalWe report the sky-projected spin–orbit angle λ for HD 191939 b, the innermost planet in a six-planet system, using Keck/KPF to detect the Rossiter–McLaughlin (RM) effect.
