Exoplanet Characterization using Conditional Invertible Neural Networks

no code implementations31 Jan 2022 Jonas Haldemann, Victor Ksoll, Daniel Walter, Yann Alibert, Ralf S. Klessen, Willy Benz, Ullrich Koethe, Lynton Ardizzone, Carsten Rother

Indeed, using cINNs allows for orders of magnitude faster inference of an exoplanet's composition than what is possible using an MCMC method, however, it still requires the computation of a large database of internal structures to train the cINN.

Internal water storage capacity of terrestrial planets and the effect of hydration on the M-R relation

no code implementations11 Dec 2020 Oliver Shah, Yann Alibert, Ravit Helled, Klaus Mezger

Here we consider three types of planets: dry interiors, hydrated interiors and dry interiors + surface ocean where the ocean mass fraction corresponds to the mass fraction of $\rm H_2 O$ equivalent in the hydrated case.

Using Deep Neural Networks to compute the mass of forming planets

1 code implementation1 Mar 2019 Yann Alibert, Julia Venturini

Computing the mass of planetary envelopes and the critical mass beyond which planets accrete gas in a runaway fashion is important when studying planet formation, in particular for planets up to the Neptune mass range.

The formation of Jupiter by hybrid pebble-planetesimal accretion

1 code implementation14 Sep 2018 Yann Alibert, Julia Venturini, Ravit Helled, Sareh Ataiee, Remo Burn, Luc Senecal, Willy Benz, Lucio Mayer, Christoph Mordasini, Sascha P. Quanz, Maria Schönbächler

The evidence that Jupiter slowed down its growth after reaching 20 Earth masses for at least 2 Myr is puzzling because a planet of this mass is expected to trigger fast runaway gas accretion.
