The Mantis Network I: A standard grid of templates and masks for cross-correlation analyses of ultra-hot Jupiter transmission spectra
Daniel Kitzmann, Jens H. Hoeijmakers, Simon L. Grimm +3
The atmospheres of ultra-hot Jupiters are highly interesting and unique chemical laboratories. Due to the very high atmospheric temperatures, their chemical composition is dominate…
An upper limit on late accretion and water delivery in the Trappist-1 exoplanet system
Sean N. Raymond, Andre Izidoro, Emeline Bolmont +9
The Trappist-1 system contains seven roughly Earth-sized planets locked in a multi-resonant orbital configuration, which has enabled precise measurements of the planets' masses and…
Titanium oxide and chemical inhomogeneity in the atmosphere of the exoplanet WASP-189b
Bibiana Prinoth, H. Jens Hoeijmakers, Daniel Kitzmann +21
The temperature of an atmosphere decreases with increasing altitude, unless a shortwave absorber exists that causes a temperature inversion. Ozone plays this role in the Earth`s at…
3D radiative-transfer for exoplanet atmospheres. gCMCRT: a GPU accelerated MCRT code
Elspeth K. H. Lee, Joost P. Wardenier, Bibiana Prinoth +10
Radiative-transfer (RT) is a key component for investigating atmospheres of planetary bodies. With the 3D nature of exoplanet atmospheres being important in giving rise to their ob…
The terrestrial planet formation paradox inferred from high-resolution N-body simulations
Jason Man Yin Woo, Ramon Brasser, Simon L. Grimm +2
Recent improvements to GPU hardware and the symplectic N-body code GENGA allow for unprecedented resolution in simulations of planet formation. In this paper, we report results fro…
Simulating gas giant exoplanet atmospheres with Exo-FMS: Comparing semi-grey, picket fence and correlated-k radiative-transfer schemes
Elspeth K. H. Lee, Vivien Parmentier, Mark Hammond +5
Radiative-transfer (RT) is a fundamental part of modelling exoplanet atmospheres with general circulation models (GCMs). An accurate RT scheme is required for estimates of the atmo…
Mars' formation can constrain the primordial orbits of the gas giants
Jason Man Yin Woo, Joachim Stadel, Simon Grimm +1
Recent high precision meteoritic data infers that Mars finished its accretion rapidly within 10 Myr of the beginning of the Solar system and had an accretion zone that did not enti…
Growing Mars fast: High-resolution GPU simulations of embryo formation
Jason Man Yin Woo, Simon L. Grimm, Ramon Brasser +1
Recent high precision meteoritic data improve constraints on the formation timescale and bulk composition of the terrestrial planets. High resolution N-body simulations allow direc…
HELIOS-K 2.0 Opacity Calculator and Open-source Opacity Database for Exoplanetary Atmospheres
Simon L. Grimm, Matej Malik, Daniel Kitzmann +12
Computing and using opacities is a key part of modeling and interpreting data of exoplanetary atmospheres. Since the underlying spectroscopic line lists are constantly expanding an…
