A nonrelativistic radiative transfer module for Idefix
Nicolas Scepi, Geoffroy Lesur
Radiation magnetohydrodynamic (RMHD) simulations are essential for comparisons with observations, particularly in the regime where fluids and radiation are dynamically coupled. Alt…
Global magnetohydrodynamic simulations of the inner regions of protoplanetary discs. II. Vertical-net-flux regime
Matthew J. O. Roberts, Henrik N. Latter, Geoffroy Lesur
The inner regions of protoplanetary discs, which encompass the putative habitable zone, are dynamically complex, featuring a relatively well-ionised, turbulent active zone located…
Magnetic winds in resistive compact binary discs
Marc Van den Bossche, Geoffroy Lesur, Guillaume Dubus
Dwarf Novae and low-mass X-ray binaries are eruptive binary systems comprised of a Roche-lobe overflowing solar-type star and an accreting compact object. Their recurrence time can…
Global magnetohydrodynamic simulations of the inner regions of protoplanetary discs. I. Zero-net flux regime
Matthew J. O. Roberts, Henrik N. Latter, Geoffroy Lesur
The inner regions of protoplanetary discs, which encompass the putative habitable zone, are dynamically complex, featuring a well-ionised, turbulent active inner region and a poorl…
High-resolution models of the vertical shear instability
Geoffroy Lesur, Henrik N. Latter, Gordon I. Ogilvie
(abridged) Context: The vertical shear instability (VSI) is a promising mechanism to generate turbulence and transport angular momentum in protoplanetary discs. While most recent w…
Gone with the wind: the outward migration of eccentric giant planets in windy disks
Gaylor Wafflard-Fernandez, Geoffroy Lesur
Recent studies indicate that circumstellar disks exhibit weak turbulence, with their dynamics and evolution being primarily influenced by magnetic winds. However, most numerical st…
