The Astronomical JournalThe present-day bulk elemental composition of an exoplanet can provide insight into a planet’s formation and evolutionary history. Such information is now being measured for dozens of planets with state-of-the-art facilities using Bayesian atmosphere ...

Effect of Laboratory Reagents for Cleaning Modern Contamination on the δ<sup>15</sup>N Integrity of Nitrogen-Poor Samples. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

The atmospheres of rocky exoplanets [PDF]
Astronomy & Astrophysics, 2022 Clouds are an integral part of planetary atmospheres, with most planets hosting clouds. Understanding not only the formation, but also the composition of clouds, is crucial to understand future observations. As observations of the planet’s surface will remain very difficult, it is essential to link the observable high atmosphere gas and cloud ...

The newly selected Venus missions EnVISION and VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) offer new opportunities for studying Venus but will also contribute to furthering our knowledge of Venus as an exoplanet. Hot rocky planets are favored targets due to generally more frequent transits than cooler Earth-like ...

Conclusive Evidence for a Population of Water Worlds around M Dwarfs Remains Elusive
The Astrophysical Journal Letters, 2023 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 rocky cores and H/He-dominated atmospheres, accounting for their thermal ...

Reflected Spectroscopy of Small Exoplanets I: Determining the Atmospheric Composition of Sub-Neptunes Planets [PDF]
The Astronomical Journal, 2021 Abstract Direct imaging of widely separated exoplanets from space will obtain their reflected light spectra and measure their atmospheric properties, and small and temperate planets will be the focus for the next generation of telescopes. In this work, we used our Bayesian retrieval algorithm
