Density-Selected Topological Pathways in the Melting of Single-Particle-Thick Stripes
José Rafael Bordin
The melting of stripe-forming systems involves changes in connectivity that are not fully captured by conventional structural and orientational descriptors. We investigate a two-di…
Metal Oxide Clusters in Gas Giant Exoplanet Atmospheres
Deepak Bisht, Christiane Helling, David Gobrecht +6
This study investigates the thermal stability and absorption of metal oxide clusters in exoplanetary atmospheres. Utilizing our thermochemical data, we analyze eight distinct clust…
Molecular diagnostics for the mid-infrared emission of planet-forming disks. Carbon and oxygen elemental abundances
Aditya M. Arabhavi, Inga Kamp, Ewine F. van Dishoeck +8
Mid-infrared observations of planet-forming disks reveal a wide diversity in molecular spectra. Carbon and oxygen abundances play a central role in setting the chemical environment…
Imaging Venus-like Worlds: Spectral, Polarimetric, and UV Diagnostics for the Habitable Worlds Observatory
Stephen R. Kane, Kimberly M. Bott, Kenneth E. Goodis Gordon +15
Understanding planetary habitability requires a comparative approach that explores the divergent evolutionary outcomes of Earth and Venus. The Habitable Worlds Observatory (HWO) wi…
Prediction of sulphate hazes in the lower Venus atmosphere
Peter Woitke, Manuel Scherf, Christiane Helling +8
We study the amount, size distribution and material composition of (sub-)mic aerosol particles in the lower Venus atmosphere < 50 km. Our GGchem phase-equilibrium model predicts me…
MINDS. Strong oxygen depletion in the inner regions of a very low-mass star disk?
Jayatee Kanwar, Inga Kamp, Peter Woitke +10
JWST is discovering a plethora of species in planet-forming disks around very low-mass stars such as C2H2, C6H6, C4H2, CH3 etc. The column densities of these species retrieved from…
