Modeling the secular evolution of embedded protoplanetary discs
J. Mauxion, G. Lesur, S. Maret
Context: Protoplanetary discs are known to form around nascent stars from their parent molecular cloud as a result of angular momentum conservation. As they progressively evolve an…
Planet-disk-wind interaction: the magnetized fate of protoplanets
Gaylor Wafflard-Fernandez, Geoffroy Lesur
Models of planet-disk interaction are mainly based on 2D and 3D viscous hydrodynamical simulations. Accretion is classically prescribed by an alpha parameter which characterizes th…
FU Orionis disk outburst: evidence for a gravitational instability scenario triggered in a magnetically dead zone
G. Bourdarot, J-P. Berger, G. Lesur +10
Context: FUors outbursts are a crucial stage of accretion in young stars. However a complete mechanism at the origin of the outburst still remains missing. Aims: We aim at constrai…
A systematic description of wind-driven protoplanetary discs
Geoffroy Lesur
(shortened) Planet forming discs are believed to be very weakly turbulent in the regions outside of 1 AU. For this reason, it is now believed that magnetized winds could be the dom…
Observations of edge-on protoplanetary disks with ALMA I. Results from continuum data
M. Villenave, F. Menard, W. R. F. Dent +15
We analyze a sample of 12 HST-selected edge-on protoplanetary disks for which the vertical extent of the emission layers can be constrained directly. We present ALMA high angular r…
Magnetohydrodynamics of protoplanetary discs
G. Lesur
Protoplanetary discs are made of gas and dust orbiting a young star. They are also the birth place of planetary systems, which motivates a large amount of observational and theoret…
