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…
