![All plot facets identical to Figure 5. Simultaneous characterization of H2O and O2. Detector noise and thermal emission are included. Shorter wavelengths are preferred for dual detection, but result in lower yields. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/Possible-Observational.png?resize=1200%2C716&ssl=1)
[astro-ph.EP] We present a variety of possible observational sequences from planet detection to characterization (i.e., survey strategies) for the initial exoEarth detection and characterization survey phase of the Habitable Worlds […]

The Venus Benchmark: Resolving Degeneracies in Terrestrial Exoplanet Spectra with DAVINCI
[astro-ph.EP]. The characterization of terrestrial exoplanets with thick, CO2-dominated atmospheres via transmission and emission spectroscopy is limited by degeneracies between atmospheric composition, cloud structure, and surface conditions.

A High Internal Heat Flux and Large Core in a Warm Neptune Exoplanet
Interactions between exoplanetary atmospheres and internal properties have long been hypothesized to be drivers of the inflation mechanisms of gaseous planets and apparent atmospheric chemical disequilibrium conditions.

On The Impact of the Vertical Structure of Martian Water Ice Clouds on Nadir Atmospheric Retrievals from Simultaneous EMM/EXI and TGO/ACS-MIR Observations
Retrieving the optical depth of the Martian clouds (τcld) is a powerful way to monitor their spatial and temporal evolution. However, such retrievals from nadir imagery rely on several assumptions, […]
