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…
The Tartu Observatory Fiber-fed Echelle Spectrograph (TOFES) Data Reduction Pipeline
Sandipan P. D. Borthakur, Tõnis Eenmäe, Nikolai Piskunov +9
We introduce the data reduction pipeline for the Tartu Observatory Fiber-fed Echelle Spectrograph (TOFES). TOFES is installed in the Coudé room and will be connected to the 1.5 m…
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…
Accelerating exoplanet climate modelling: A machine learning approach to complement 3D GCM grid simulations
Alexander Plaschzug, Amit Reza, Ludmila Carone +2
With the development of ever-improving telescopes capable of observing exoplanet atmospheres in greater detail and number, there is a growing demand for enhanced 3D climate models…
Grid-based exoplanet atmospheric mass loss predictions through neural network
Amit Reza, Daria Kubyshkina, Luca Fossati +1
The fast and accurate estimation of planetary mass-loss rates is critical for planet population and evolution modelling. We use machine learning (ML) for fast interpolation across…
Kinetic and photochemical disequilibrium in the potentially carbon-rich atmosphere of the warm-Jupiter WASP-69b
Nidhi Bangera, Christiane Helling, Gloria Guilluy +5
High-resolution transmission spectroscopy of the warm gas-giant WASP-69b has revealed the presence of H2O, CO, CH4, NH3, and C2H2 in its atmosphere. This study investigates the imp…
