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…
Photoevaporation of protoplanetary discs with PLUTO+PRIZMO I. Lower X-ray-driven mass-loss rates due to enhanced cooling
Andrew D. Sellek, Tommaso Grassi, Giovanni Picogna +3
Context: Photoevaporation is an important process for protoplanetary disc dispersal but there has so far been a lack of consensus from simulations over the mass-loss rates and the…
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…
