Astronomische Nachrichten, Volume 347, Issue 1, January 2026.ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

Olivine‐Ahrensite Phase Relations in the Mg2SiO4‐Fe2SiO4 System as a Function of Temperature
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Olivine and ahrensite are the primary components of the interiors of Fe‐rich terrestrial planets and meteorites, making their phase relations crucial for planetary science. Moreover, their phase relations can be used for calibrating large‐volume high‐pressure devices such as multi‐anvil apparatus.

Impacting Atmospheres: How Late-stage Pollution Alters Exoplanet Composition
The Astrophysical JournalThe atmospheric composition of exoplanets is often considered as a probe of the planet’s formation conditions. How exactly the initial chemical memory may be altered from the birth to the final state of the planet, however, remains unknown.

The Astrophysical Journal, 2023 Atmospheric nitrogen may provide important constraints on giant planet formation. Following our semianalytical work, we further pursue the relation between observable NH _3 and an atmosphere’s bulk nitrogen abundance by applying the photochemical ...

petitRADTRANS: a Python radiative transfer package for exoplanet characterization and retrieval
, 2019 We present the easy-to-use, publicly available, Python package petitRADTRANS, built for the spectral characterization of exoplanet atmospheres. The code is fast, accurate, and versatile; it can calculate both transmission and emission spectra within a ...

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,

Most Super-Earths Have Less Than 3% Water
The Astrophysical JournalSuper-Earths are highly irradiated, small planets with bulk densities approximately consistent with Earth. We construct combined interior atmosphere models of super-Earths that trace the partitioning of water throughout a planet, including an iron-rich ...

A Population of Very-Hot Super-Earths in Multiple-Planet Systems Should be Uncovered by Kepler
, 2010 We simulate a Kepler-like observation of a theoretical exoplanet population and we show that the observed orbital period distribution of the Kepler giant planet candidates is best matched by an average stellar specific dissipation function Q_* in the ...
