THOR 2.0: Major Improvements to the Open-Source General Circulation Model
Russell Deitrick, João M. Mendonça, Urs Schroffenegger +3
THOR is the first open-source general circulation model (GCM) developed from scratch to study the atmospheres and climates of exoplanets, free from Earth- or Solar System-centric t…
Interpreting High-Resolution Spectroscopy of Exoplanets Using Cross-Correlations and Supervised Machine Learning
Chloe Fisher, H. Jens Hoeijmakers, Daniel Kitzmann +4
We present a new method for performing atmospheric retrieval on ground-based, high-resolution data of exoplanets. Our method combines cross-correlation functions with a random fore…
Helios-r2 -- A new Bayesian, open-source retrieval model for brown dwarfs and exoplanet atmospheres
Daniel Kitzmann, Kevin Heng, Maria Oreshenko +5
We present an improved, hybrid CPU-GPU atmospheric retrieval code, Helios-r2, which is applicable to medium-resolution emission spectra of brown dwarfs, in preparation for precisio…
Exoplanetary Monte Carlo Radiative Transfer with Correlated-k I. Benchmarking Transit and Emission Observables
Elspeth K. H. Lee, Jake Taylor, Simon L. Grimm +4
Current observational data of exoplanets are providing increasing detail of their 3D atmospheric structures. As characterisation efforts expand in scope, the need to develop consis…
A spectral survey of an ultra-hot Jupiter: Detection of metals in the transmission spectrum of KELT-9 b
H. J. Hoeijmakers, D. Ehrenreich, D. Kitzmann +16
Context: KELT-9 b exemplifies a newly emerging class of short-period gaseous exoplanets that tend to orbit hot, early type stars - termed ultra-hot Jupiters. The severe stellar irr…
ExoMol Molecular linelists -- XXXIII. The spectrum of Titanium Oxide
Laura K. McKemmish, Thomas Masseron, H. Jens Hoeijmakers +4
Accurate line lists are crucial for correctly modelling a variety of astrophysical phenomena, including stellar photospheres and the atmospheres of extra-solar planets. This paper…
Self-luminous and irradiated exoplanetary atmospheres explored with HELIOS
Matej Malik, Daniel Kitzmann, João M. Mendonça +5
We present new methodological features and physical ingredients included in the 1D radiative transfer code HELIOS, improving the hemispheric two-stream formalism. We conduct a thor…
Co-orbital exoplanets from close period candidates: The TOI-178 case
Adrien Leleu, Jorge Lillo-Box, Marko Sestovic +6
Despite the existence of co-orbital bodies in the solar system, and the prediction of the formation of co-orbital planets by planetary system formation models, no co-orbital exopla…
