Super-Earth Interiors Shrink by About 10% as They Crystallise
Tim Lichtenberg, Mara Attia, Harrison Nicholls +26
Super-Earth exoplanets are among the most abundant planets known, yet their bulk densities leave the interior state degenerate. The static structure models used to interpret them,…
Atmospheric evolution through outgassing and escape on young molten rocky exoplanets
Emma Postolec, Tim Lichtenberg, Harrison Nicholls +2
The earliest rocky planet atmospheres are shaped by competition between initial volatile inventories and atmospheric escape. On young magma ocean planets, outgassing competes with…
Geophysical and atmospheric implications of O-dependent melting on rocky exoplanets
Mariana Sastre, Tim Lichtenberg, Laurent Soucasse +3
The geochemical evolution of long-lived magma oceans is strongly regulated by volatile exchange between the molten mantle and the atmosphere. For planets inside the runaway-greenho…
Constructing efficient score functions for rare event simulation in high-dimensional ocean-climate models
Lucas Esclapez, Valérian Jacques-Dumas, Reyk Börner +2
Calculating transition probabilities between different states of multistable climate tipping systems is computationally challenging in high-dimensional models. Targeted algorithms,…
Coupled atmospHere Interior modeL Intercomparison (CHILI) Protocol Version 1.0: A CUISINES Intercomparison Project of Magma Ocean Models
Tim Lichtenberg, Laura Schaefer, Joshua Krissansen-Totton +23
Spectroscopic characterization of rocky exoplanets with the James Webb Space Telescope has brought the origin and evolution of their atmospheres into the focus of exoplanet science…
Accelerating the Dutch Atmospheric Large-Eddy Simulation (DALES) model with OpenACC
Lucas Esclapez, Laurent Soucasse, Caspar Jungbacker +5
This paper presents the GPU porting through OpenACC directives of the Dutch Atmospheric Large-Eddy Simulation (DALES) application, a high-resolution atmospheric model. The code is…
Convective shutdown in the atmospheres of lava worlds
Harrison Nicholls, Raymond T. Pierrehumbert, Tim Lichtenberg +2
Atmospheric energy transport is central to the cooling of primordial magma oceans. Theoretical studies of atmospheres on lava planets have assumed that convection is the only proce…
Dissipation-based proper orthogonal decomposition of turbulent Rayleigh-Bénard convection flow
Peder Jørgensgaard Olesen, Laurent Soucasse, Bérengère Podvin +1
We present a formulation of proper orthogonal decomposition (POD) producing a velocity-temperature basis optimized with respect to an dissipation norm. This decomposition is…
Tulipa Energy Model: Mathematical Formulation
Diego A. Tejada-Arango, Germán Morales-España, Lauren Clisby +5
Tulipa Energy Model aims to optimise the investment and operation of the electricity market, considering its coupling with other sectors, such as hydrogen and heat, that can also b…
On the analysis of Rayleigh-Bénard convection using Latent Dirichlet Allocation
Bérengère Podvin, Laurent Soucasse, François Yvon
We apply a probabilistic clustering method, Latent Dirichlet Allocation (LDA), to characterize the largescale dynamics of Rayleigh-Bénard convection. The method, introduced in Frih…
Role of solutal free convection on interdiffusion in a horizontal microfluidic channel
Jean-Baptiste Salmon, Laurent Soucasse, Frédéric Doumenc
We theoretically investigate the role of solutal free convection on the diffusion of a buoyant solute at the microfluidic scales, --m. We first consider a horizont…
