Core and mantle thermal evolution constraints on the onset of plate tectonics and a long-lived geodynamo
Valentin Bonnet Gibet, Nicola Tosi
Earth's long-lived geodynamo is difficult to reconcile with recent high estimates of the core thermal conductivity, a problem known as the new core paradox. At the same time, the l…
The influence of interior structure and thermal state on impact melt generation upon large impacts onto terrestrial planets
Lukas Manske, Thomas Ruedas, Ana-Catalina Plesa +4
We investigate the melt production of planetary impacts as a function of planet size (=0.1-1.5), impactor size (=1-1000 km), and core size ratio ($R_\mathrm{…
Physics-based machine learning for mantle convection simulations
Siddhant Agarwal, Ali Can Bekar, Christian Hüttig +2
Mantle convection simulations are an essential tool for understanding how rocky planets evolve. However, the poorly known input parameters to these simulations, the non-linear depe…
The effect of a biosphere on the habitable timespan of stagnant-lid planets and implications for the atmospheric spectrum
Dennis Höning, Ludmila Carone, Philipp Baumeister +6
Temperature-dependent biological productivity controls silicate weathering and thereby extends the potential habitable timespan of Earth. Models and theoretical considerations indi…
H-HO demixing in Uranus and Neptune: Adiabatic structure models
Marina Cano Amoros, Nadine Nettelmann, Nicola Tosi +2
Demixing properties of planetary major constituents influence the interior structure and evolution of planets. Comparing experimental and computational data on the miscibility of h…
Accelerating the discovery of steady-states of planetary interior dynamics with machine learning
Siddhant Agarwal, Nicola Tosi, Christian Hüttig +2
Simulating mantle convection often requires reaching a computationally expensive steady-state, crucial for deriving scaling laws for thermal and dynamical flow properties and bench…
Geodynamics of super-Earth GJ 486b
Tobias G. Meier, Dan J. Bower, Tim Lichtenberg +8
Many super-Earths are on very short orbits around their host star and, therefore, more likely to be tidally locked. Because this locking can lead to a strong contrast between the d…
Atmospheric Helium Abundances in the Giant Planets
N. Nettelmann, M. Cano Amoros, N. Tosi +2
Noble gases are accreted to the giant planets as part of the gas component of the planet-forming disk. While heavier noble gases can separate from the evolution of the hydrogen-ric…
ExoMDN: Rapid characterization of exoplanet interior structures with Mixture Density Networks
Philipp Baumeister, Nicola Tosi
Characterizing the interior structure of exoplanets is essential for understanding their diversity, formation, and evolution. As the interior of exoplanets is inaccessible to obser…
Redox state and interior structure control on the long-term habitability of stagnant-lid planets
Philipp Baumeister, Nicola Tosi, Caroline Brachmann +2
A major goal in the search for extraterrestrial life is the detection of liquid water on the surface of exoplanets. On terrestrial planets, volcanic outgassing is a significant sou…
Planetary Exploration Horizon 2061 Report, Chapter 3: From science questions to Solar System exploration
Véronique Dehant, Michel Blanc, Steve Mackwell +31
This chapter of the Planetary Exploration Horizon 2061 Report reviews the way the six key questions about planetary systems, from their origins to the way they work and their habit…
Residence time of inertial particles in 3D thermal convection: implications for magma reservoirs
Vojtěch Patočka, Nicola Tosi, Enrico Calzavarini
The dynamic behavior of crystals in convecting fluids determines how magma bodies solidify. In particular, it is often important to estimate how long crystals stay in suspension in…
Early habitability and crustal decarbonation of a stagnant-lid Venus
Dennis Höning, Philipp Baumeister, John Lee Grenfell +2
Little is known about the early evolution of Venus and a potential habitable period during the first one billion years. In particular, it remains unclear whether or not plate tecto…
Deep learning for surrogate modelling of 2D mantle convection
Siddhant Agarwal, Nicola Tosi, Pan Kessel +2
Traditionally, 1D models based on scaling laws have been used to parameterized convective heat transfer rocks in the interior of terrestrial planets like Earth, Mars, Mercury and V…
Settling of inertial particles in turbulent Rayleigh-Benard convection
Vojtech Patocka, Enrico Calzavarini, Nicola Tosi
The settling behaviour of small inertial particles in turbulent convection is a fundamental problem across several disciplines, from geophysics to metallurgy. In a geophysical cont…
Mercury, Moon, Mars: Surface expressions of mantle convection and interior evolution of stagnant-lid bodies
Nicola Tosi, Sebastiano Padovan
The evolution of the interior of stagnant-lid bodies is comparatively easier to model and predict with respect to the Earth's due to the absence of the large uncertainties associat…
Machine learning inference of the interior structure of low-mass exoplanets
Philipp Baumeister, Sebastiano Padovan, Nicola Tosi +4
We explore the application of machine learning based on mixture density neural networks (MDNs) to the interior characterization of low-mass exoplanets up to 25 Earth masses constra…
Carbon cycling and interior evolution of water-covered plate tectonics and stagnant lid planets
Dennis Höning, Nicola Tosi, Tilman Spohn
Aims: The long-term carbon cycle for planets with a surface entirely covered by oceans works differently from that of the present-day Earth because inefficient erosion leads to a s…
What factors affect the duration and outgassing of the terrestrial magma ocean?
Athanasia Nikolaou, Nisha Katyal, Nicola Tosi +3
The magma ocean (MO) is a crucial stage in the build-up of terrestrial planets. Its solidification and the accompanying outgassing of volatiles set the conditions for important pro…
The habitability of stagnant-lid Earths around dwarf stars
Mareike Godolt, Nicola Tosi, Barbara Stracke +4
The habitability of a planet depends on various factors, such as delivery of water during the formation, the co-evolution of the interior and the atmosphere, as well as the stellar…
Evolution and Spectral Response of a Steam Atmosphere for Early Earth with a coupled climate-interior model
Nisha Katyal, Athanasia Nikolaou, Mareike Godolt +4
The evolution of Earth's early atmosphere and the emergence of habitable conditions on our planet are intricately coupled with the development and duration of the magma ocean phase…
Bifurcation in the growth of continental crust
Dennis Höning, Nicola Tosi, Hendrik Hansen-Goos +1
Is the present-day water-land ratio a necessary outcome of the evolution of plate tectonic planets with a similar age, volume, mass, and total water inventory as the Earth? This wo…
Matrix-propagator approach to compute fluid Love numbers and applicability to extrasolar planets
S. Padovan, T. Spohn, P. Baumeister +5
Context. The mass and radius of a planet directly provide its bulk density, which can be interpreted in terms of its overall composition. Any measure of the radial mass distributio…
The habitability of a stagnant-lid Earth
N. Tosi, M. Godolt, B. Stracke +7
