Characterizing the bolometric-photoevaporative transition in young sub-Neptunes with radiation-hydrodynamic simulations
William Misener, Matthäus Schulik, Hilke E. Schlichting +1
Hydrodynamic atmospheric escape plays a central role in shaping the demographics of small, close-in exoplanets. Two mechanisms have been proposed to drive mass loss: photoevaporati…
Stringent Upper Bounds on Atmospheric Mass Loss from Three Neptune-Sized Planets in the TOI-4010 System
Morgan Saidel, Shreyas Vissapragada, Michael Zhang +6
Photoevaporative models predict that the lower edge of the Neptune desert is sculpted by atmospheric mass loss. However, the stellar high energy fluxes that power hydrodynamic esca…
Efficient and inefficient hydrodynamic escape of exo-satellite atmospheres driven by irradiation from their young giant planets
Matthäus Schulik, James E. Owen, Richard A. Booth +2
The bolometric radiation from a central body is potentially a powerful driver of atmospheric escape from planets or satellites. When heated above their equilibrium temperatures tho…
The influence of dust growth on the observational properties of circumplanetary discs
Matthäus Schulik, Bertram Bitsch, Anders Johansen +1
Dust growth is often indirectly inferred observationally in star-forming environments, theoretically predicted to produce mm-sized particles in circumstellar discs, and also presum…
Using the helium triplet as a tracer of the physics of giant planet outflows
Matthäus Schulik, James Owen
Hydrodynamic outflows, such as those observed escaping close-in gas giant planets, are not isothermal in structure. Their highly ionized nature allows them to cool adiabatically at…
Gas dynamics around a Jupiter-mass planet I. Influence of protoplanetary disk properties
E. Lega, M. Benisty, A. Cridland +3
Giant planets grow and acquire their gas envelope during the disk phase. At the time of the discovery of giant planets in their host disk, it is important to understand the interpl…
Blowin' in the non-isothermal wind: core-powered mass loss with hydrodynamic radiative transfer
William Misener, Matthäus Schulik, Hilke E. Schlichting +1
The mass loss rates of planets undergoing core-powered escape are usually modeled using an isothermal Parker-type wind at the equilibrium temperature, . However, the…
Aiolos- A multi-purpose 1-D hydrodynamics code for planetary atmospheres
Matthäus Schulik, Richard Booth
We present a new 1-D multi-physics simulation code with use cases intended for, but not limited to, hydrodynamic escapeproblems of planetary atmospheres and planetary accretion mod…
Interpreting the atmospheric composition of exoplanets: sensitivity to planet formation assumptions
Paul Mollière, Tamara Molyarova, Bertram Bitsch +13
Constraining planet formation based on the atmospheric composition of exoplanets is a fundamental goal of the exoplanet community. Existing studies commonly try to constrain atmosp…
Dust formation in the outflows of catastrophically evaporating planets
Richard A. Booth, James E. Owen, Matthäus Schulik
Ultra-short period planets offer a window into the poorly understood interior composition of exoplanets through material evaporated from their rocky interiors. Among these objects…
On the structure and mass delivery towards circumplanetary discs
Matthäus Schulik, Anders Johansen, Bertram Bitsch +2
Circumplanetary discs (CPDs) form around young gas giants and are thought to be the sites of moon formation as well as an intermediate reservoir of gas that feeds the growth of the…
Global 3D radiation-hydrodynamic simulations of gas accretion: The opacity dependent growth of Saturn-mass planets
Matthäus Schulik, Anders Johansen, Bertram Bitsch +1
The full spatial structure and temporal evolution of the accretion flow into the envelopes of growing gas giants in their nascent discs is only accessible in simulations. Such simu…
