Small Collisions, Big Impact: The Sensitivity of Atmospheric Temperatures to Collision-Induced Absorption
David Dahlbüdding, Tommaso Grassi, Karan Molaverdikhani +3
Collision-induced absorption (CIA) data are relevant to determining atmospheric temperatures and, in turn, the habitability of a diverse set of planetary atmospheres. However, thes…
Probing Exoplanetary Chemistry with Ariel: Scientific Priorities and Observational Strategies
Olivia Venot, Yamila Miguel, Robin Baeyens +30
Over the past two decades, increasingly precise observations have revealed that exoplanet atmospheres are chemically diverse and often far from equilibrium, with processes such as…
Atmospheric retrieval evidence for water isotopologue HDO on exoplanet WASP-39b
Fabian Gruebel, Karan Molaverdikhani, Barbara Ercolano +5
Hydrogen-isotopologues are commonly used to trace the chemical processing and origin of hydrogen-bearing species throughout the Universe, however, their abundance remains unconstra…
Habitability of Tidally Heated H-Dominated Exomoons around Free-Floating Planets
David Dahlbüdding, Tommaso Grassi, Karan Molaverdikhani +4
Exomoons around free-floating planets (FFPs) can survive their host planet's ejection. Such ejections can increase their orbital eccentricity, providing significant tidal heating i…
Deep Mantle-Atmosphere Coupling and Carbonaceous Bombardment: Options for Biomolecule Formation on an Oxidized Early Earth
Klaus Paschek, Thomas K. Henning, Karan Molaverdikhani +4
Understanding what environmental conditions prevailed on early Earth during the Hadean eon, and how this set the stage for the origins of life, remains a challenge. Geologic proces…
Polycyclic Aromatic Hydrocarbons (PAHs) as an Extraterrestrial Atmospheric Technosignature
Dwaipayan Dubey, Ravi Kopparapu, Barbara Ercolano +1
Polycyclic Aromatic Hydrocarbons are prevalent in the universe and interstellar medium but are primarily attributed to anthropogenic sources on Earth, such as fossil fuel combustio…
Detectability of Polycyclic Aromatic Hydrocarbons in the Atmosphere of WASP-6 b with JWST NIRSpec PRISM
Fabian Grübel, Karan Molaverdikhani, Barbara Ercolano +4
Polycyclic Aromatic Hydrocarbons (PAHs) have been detected throughout the universe where they play essential roles in the evolution of their environments. For example, they are bel…
Polycyclic Aromatic Hydrocarbons in Exoplanet Atmospheres: A Detectability Study
Rosa Arenales-Lope, Karan Molaverdikhani, Dwaipayan Dubey +3
In this paper, we explore the detectability of polycyclic aromatic hydrocarbons (PAHs) under diverse planetary conditions, aiming to identify promising targets for future observati…
Approximating Rayleigh Scattering in Exoplanetary Atmospheres using Physics-informed Neural Networks (PINNs)
David Dahlbüdding, Karan Molaverdikhani, Barbara Ercolano +1
This research introduces an innovative application of physics-informed neural networks (PINNs) to tackle the intricate challenges of radiative transfer (RT) modeling in exoplanetar…
The case for studying other planetary magnetospheres and atmospheres in Heliophysics
Ian J. Cohen, Chris Arridge, Abigail Azari +37
Heliophysics is the field that "studies the nature of the Sun, and how it influences the very nature of space - and, in turn, the atmospheres of planetary bodies and the technology…
Polycyclic Aromatic Hydrocarbons in Exoplanet Atmospheres I. Thermochemical Equilibrium Models
Dwaipayan Dubey, Fabian Grübel, Rosa Arenales-Lope +4
Context: Polycyclic Aromatic Hydrocarbons, largely known as PAHs, are widespread in the universe and have been identified in a vast array of astronomical observations from the inte…
Presence of liquid water during the evolution of exomoons orbiting ejected free-floating planets
Giulia Roccetti, Tommaso Grassi, Barbara Ercolano +4
Free-floating planets (FFPs) can result from dynamical scattering processes happening in the first few million years of a planetary system's life. Several models predict the possib…
Photochemically-produced SO in the atmosphere of WASP-39b
Shang-Min Tsai, Elspeth K. H. Lee, Diana Powell +82
Photochemistry is a fundamental process of planetary atmospheres that regulates the atmospheric composition and stability. However, no unambiguous photochemical products have been…
