A Framework for Quantifying the Degeneracies of Exoplanet Interior Compositions
, 2010 Several transiting super-Earths are expected to be discovered in the coming few years. While tools to model the interior structure of transiting planets exist, inferences about the composition are fraught with ambiguities.

New Phytologist, EarlyView.Summary One‐carbon (C1) metabolism, centered on the universal methyl donor S‐adenosyl methionine (SAM), plays critical roles in biosynthesis, redox regulation, and stress responses across plants and microbes. A recently proposed photosynthetic C1 pathway links SAM methyl groups directly to RuBisCO‐mediated CO2 assimilation and integrates with nitrogen ...

Unveiling the atmospheric evolution of exoplanets
, 2021 A thorough characterisation of an exoplanetary system includes also studying the evolution of planetary atmospheres. To this end, we developed a custom tool to estimate the atmospheric content of exoplanets at the dispersal of the protoplanetary disk accounting for the present day system observables. In detail, our tool relies on planetary evolutionary

The Astronomical JournalTOI-836 is a ∼2–3 Gyr K dwarf with an inner super Earth ( R = 1.7 R _⊕ , P = 3.8 days) and an outer mini-Neptune ( R = 2.6 R _⊕ , P = 8.6 days). JWST/NIRSpec 2.8–5.2 μ m transmission spectra are flat for both planets.

TOI-1695 b: A Water World Orbiting an Early-M Dwarf in the Planet Radius Valley
The Astronomical Journal, 2023 Characterizing the bulk compositions of transiting exoplanets within the M dwarf radius valley offers a unique means to establish whether the radius valley emerges from an atmospheric mass-loss process or is imprinted by planet formation itself.

The ARCiS framework for Exoplanet Atmospheres: The Cloud Transport Model [PDF]
, 2019 Understanding of clouds is instrumental in interpreting current and future spectroscopic observations of exoplanets. Modelling clouds consistently is complex, since it involves many facets of chemistry, nucleation theory, condensation physics ...

Strong Fractionation of Deuterium and Helium in Sub-Neptune Atmospheres along the Radius Valley
The Astrophysical JournalWe simulate atmospheric fractionation in escaping planetary atmospheres using IsoFATE , a new open-source numerical model. We expand the parameter space studied previously to planets with tenuous atmospheres that exhibit the greatest helium and deuterium

Spectral Evolution of an Earth-Like Planet [PDF]
, 2006 We have developed a characterization of the geological evolution of the Earths atmosphere and surface in order to model the observable spectra of an Earth-like planet through its geological history.

The Power of a Name: Toward a Unified Approach to Naming Space Weather Events
Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.Abstract Our increasing reliance on technology vulnerable to space weather effects underscores the urgent need for effective public communication about these phenomena. While scientific research thrives on precise technical language, broader public engagement necessitates a more accessible and memorable approach.
