How uncertainties on stellar atmospheric parameters impact exoplanet studies? [PDF]
, 2017 Exoplanet properties depend on how well the host star is characterized. For instance, the stellar atmospheric parameters (i.e., effective temperature, surface gravity and overall metallicity) are needed to derive the stellar mass and radius by using ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory
Astronomische Nachrichten, Volume 347, Issue 7, August 2026.ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

A Theory for the Global Wind Energy Dissipation Across Climates
AGU Advances, Volume 7, Issue 5, August 2026.Abstract Atmospheric winds play a key role in shaping climate, ecosystems, and infrastructure. The energy that drives the winds is generated by the atmospheric heat engine. However, traditional entropy‐budget descriptions of this heat engine rely on poorly constrained microscale processes, limiting their predictive power.

Reinterpreting the JWST Observations of 55 Cancri e with a Nongray General Circulation Model
The Astrophysical JournalRecent observations of 55 Cancri e suggest an atmosphere rich in CO or CO _2 ; other observations indicate the planet’s eclipse depth is highly variable.

Atmospheric Circulation of High-obliquity Mini-Neptunes
The Astrophysical JournalWith the operation of JWST, atmospheric characterization has now extended to low-mass exoplanets. In compact multiplanetary systems, secular spin-orbital resonance may preserve high obliquities and asynchronous rotation even for tidally despinning, low ...

The Complexity of Deep Aqueous Fluids in Planetary Ultramafic Mantles
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract Planetary volatiles cycle through a planet's crust, mantle, and atmosphere, playing a crucial role in surface processes and habitability. Discussions of planetary volatiles traditionally focus on water, carbon, nitrogen, and sulfur, but fluids in contact with silicate rocks and ultramafic mantles can contain significant amounts of magnesium ...
