Solar carbon abundance from 3D non-LTE modelling of the diagnostic lines of the CH molecule
Richard Hoppe, Maria Bergemann, Philipp Eitner +5
The spectral lines of the CH molecule are a key carbon (C) abundance diagnostic in FGKM-type stars. These lines are detectable in metal-rich and, in contrast to atomic C lines, als…
GPU accelerated MHD in the DISPATCH framework using directive-based programming
Michael Haahr, Troels Haugbølle, Åke Nordlund +2
We present a GPU-accelerated implementation of a magnetohydrodynamic (MHD) solver using directive-based programming with OpenMP target offloading. The solver is integrated into the…
Abundance Effects from Protoplanetary Disk Outflows
Åke Nordlund
Systematic abundance differences that depend on the condensation temperatures of elements have been observed, in particular for stars similar to the Sun; solar twins and solar anal…
Thousands of planetesimals: Simulating the streaming Instability in very large computational domains
Urs Schäfer, Anders Johansen, Troels Haugbølle +1
The streaming instability is a mechanism whereby pebble-sized particles in protoplanetary discs spontaneously come together in dense filaments, which collapse gravitationally to fo…
A grid of self-consistent MSG (MARCS-StaticWeather-GGchem) cool stellar, sub-stellar, and exoplanetary model atmospheres
Uffe G. Jørgensen, Flavia Amadio, Beatriz Campos Estrada +8
Computation of a grid of self consistent 1D model atmospheres of cool stars, sub-stellar objects and exoplanets in the effective temperature range 300K to 3000K, including cloud fo…
The Stagger Code for Accurate and Efficient, Radiation-Coupled MHD Simulations
Robert F. Stein, Åke Nordlund, Remo Collet +1
We describe the Stagger Code for simulations of magneto-hydrodynamic (MHD) systems. This is a modular code with a variety of physics modules that will let the user run simulations…
