Accretion across scales: streamers, surface-layer transport, and rapid replenishment in young protoplanetary discs
Christian Granzow Holm, Michiel Lambrechts, Michael Kuffmeier +3
Protoplanetary discs evolve around newly-formed stars through an interplay of infall from surrounding turbulent cloud material, accretion towards the young star, and outflow driven…
RAMSES-GPU: Cell-by-Cell Adaptive Mesh Refinement with Magneto-Hydrodynamics and Self-Gravity on Graphics Processing Units
Romain Teyssier, Eric Moseley, Robert V. Caddy +9
We present the implementation and optimization of the cosmological simulation code RAMSES on Graphics Processing Units (GPUs) using CUDA Fortran. This accelerated version ports the…
Interstellar Ices as Carriers of Supernova Material to the Early Solar System
Martin Bizzarro, Martin Schiller, Jesper Holst +10
Planetary materials show systematic variations in their nucleosynthetic isotope compositions that resonate with orbital distance. The origin of this pattern remains debated, limiti…
Preferential accretion of binary stars
Daniel Dalsgaard, Michael Kuffmeier, Troels Haugbølle
The attracting properties of gravity enable matter present in cores to collapse into stars with seven orders of magnitude change in space and time making modelling of star formatio…
GPU accelerated MHD in the DISPATCH framework using directive-based programming
Michael Haahr, Troels Haugbølle, à ke 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…
The Formation of Protoplanetary Disks through Pre-Main Sequence Bondi-Hoyle Accretion
Paolo Padoan, Liubin Pan, Veli-Matti Pelkonen +2
Protoplanetary disks are traditionally described as finite mass reservoirs left over by the gravitational collapse of the protostellar core, a view that strongly constrains both di…
