The First Evidence of a Host Star Metallicity Cutoff in the Formation of Super-Earth Planets
The Astronomical JournalPlanet formation is expected to be severely limited in disks of low metallicity, owing to both the small solid mass reservoir and the low-opacity accelerating the disk gas dissipation.

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.Abstract Thermophysical properties of silicate liquids under extreme conditions are critical for understanding the accretion and evolution of super‐Earths and sub‐Neptunes. The thermal equation of state and viscosity of silicate liquids determine the adiabatic profiles and dynamics of magma oceans. However, these properties are challenging to constrain

An Updated Study of Potential Targets for Ariel [PDF]
, 2019 Ariel has been selected as ESA's M4 mission for launch in 2028 and is designed for the characterisation of a large and diverse population of exoplanetary atmospheres to provide insights into planetary formation and evolution within our Galaxy.

Journal of Geophysical Research: Space Physics, Volume 130, Issue 3, March 2025.Abstract We investigate Mercury's response to rare, low Alfvénic Mach number MA $\left({M}_{A}\right)$ solar wind conditions using observations from the Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) mission. This study provides compelling evidence of Mercury's altered magnetospheric state under these extreme conditions ...

Bayesian analysis of interiors of HD 219134b, Kepler-10b, Kepler-93b, CoRoT-7b, 55 Cnc e, and HD 97658b using stellar abundance proxies [PDF]
, 2016 Using a generalized Bayesian inference method, we aim to explore the possible interior structures of six selected exoplanets for which planetary mass and radius measurements are available in addition to stellar host abundances: HD~219134b, Kepler-10b ...

Astrometry of directly imaged exoplanets with optical interferometry
Comptes Rendus. Physique, 2023 Optical interferometry has always been seen as a promising but difficult technique for astronomy. Until the year 2018, it was excrucially limited in sensitivity to magnitudes below 10.

Is OSSO a Significant Contributor to the Unknown UV Absorber in Venus' Atmosphere?
Geophysical Research Letters, Volume 52, Issue 4, 28 February 2025.Abstract It has been proposed that two isomers of the SO dimer (cis‐ and trans‐OSSO) are candidates for the unknown UV absorber in Venus' atmosphere because they have a good spectral match with the absorber, despite the low concentrations predicted by 1D photochemical models.

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.
