Nautilus Space Observatory: Unveiling the Diversity and Origin of Sub-Neptunes
[astro-ph.IM] Sub-Neptunes are the most common class of planets in the Galaxy, yet they have no Solar System analog and remain poorly understood as a population. JWST observations have revealed […]

White Paper On Phototrophic Biosignatures: Research Priorities For The Search For Life On Other Worlds
[astro-ph.IM] Photosynthesis is of prime interest in the telescopic search for life beyond the Solar System, because, on Earth, oxygenic photosynthesis produces two strong “biosignatures,” global scale signs of life […]

A Scalable Path to Astrometric Exomoon Discoveries with the Nautilus Space Observatory
[astro-ph.IM] Moons orbiting exoplanets (exomoons) can be detected through the reflex motion they impart to their host planet, which is recoverable in relative star-planet astrometric time series.

Photochemical Production of CS2 in Temperate-to-Warm Gas Giant Exoplanet Atmospheres
[astro-ph.EP] Sulfur chemistry has emerged as an important probe of exoplanet atmospheres in the JWST era, although observational constraints have thus far been largely limited to SO2 and H2S in […]

Planet Formation In Chemically Diverse And Evolving Discs II. Chemical Fingerprints In Planetary Atmospheres
[astro-ph.EP] Giant planets form in protoplanetary discs, where the coupled dynamical and chemical evolution of gas and solids determines the composition of the material they accrete. We investigate how planet […]
