Full one-fluid dusty gas with multiple grain species in SPH
Mark Hutchison, Guillaume Laibe, Giovanni Tedeschi-Prades +5
We present a Smoothed Particle Hydrodynamics (SPH) implementation of the full one-fluid dusty gas algorithm for multiple dust species, generalising our previous terminal velocity a…
A highly accurate drag solver for multi-fluid dust and gas hydrodynamics on GPUs
L. Sewanou, G. Laibe, B. Commerçon
Exascale supercomputing unleashes the potential for simulations of astrophysical systems with unprecedented resolution. Taking full advantage of this computing power requires the d…
The Shamrock code: I- Smoothed Particle Hydrodynamics on GPUs
Timothée David--Cléris, Guillaume Laibe, Yona Lapeyre
We present Shamrock, a performance portable framework developed in C++17 with the SYCL programming standard, tailored for numerical astrophysics on Exascale architectures. The core…
Weighing protoplanetary discs with kinematics: physical model, method and benchmark
Benedetta Veronesi, Cristiano Longarini, Giuseppe Lodato +4
The mass of protoplanetary discs sets the amount of material available for planet formation, determines the level of coupling between gas and dust, and possibly sets gravitational…
Probing the eccentricity in protostellar discs -- Modeling kinematics and morphologies
Enrico Ragusa, Elliot Lynch, Guillaume Laibe +2
Protostellar discs are mostly modelled as circular structures of gas and dust orbiting a protostar. However, a number of physical mechanisms, e.g. the presence of a (sub)stellar co…
A Local Model for the Spherical Collapse/Expansion Problem
Elliot M. Lynch, Guillaume Laibe
Spherical flows are a classic problem in astrophysics which are typically studied from a global perspective. However, much like with accretion discs, there are likely many instabil…
