Topological modes in stellar oscillations
Armand Leclerc, Guillaume Laibe, Pierre Delplace +2
Stellar oscillations can be of topological origin. We reveal this deep and so-far hidden property of stars by establishing a novel parallel between stars and topological insulators…
Large dust fractions can prevent the propagation of soundwaves
Timothée David--Cléris, Guillaume Laibe
Dust plays a central role in several astrophysical processes. Hence the need of dust/gas numerical solutions, and analytical problems to benchmark them. In the seminal dustywave pr…
Protostellar collapse: the conditions to form dust rich protoplanetary disks
Ugo Lebreuilly, Benoît Commerçon, Guillaume Laibe
Dust plays a key role during star, disk and planet formation. Yet, its dynamics during the protostellar collapse remains a poorly investigated field. Recent studies seem to indicat…
Circumbinary, not transitional: On the spiral arms, cavity, shadows, fast radial flows, streamers and horseshoe in the HD142527 disc
Daniel J. Price, Nicolas Cuello, Christophe Pinte +13
We present 3D hydrodynamical models of the HD142527 protoplanetary disc, a bright and well studied disc that shows spirals and shadows in scattered light around a 100 au gas cavity…
An opening criterion for dust gaps in protoplanetary discs
Giovanni Dipierro, Guillaume Laibe
We aim to understand under which conditions a low mass planet can open a gap in viscous dusty protoplanetary discs. For this purpose, we extend the theory of dust radial drift to i…
On the maximum grain size entrained by photoevaporative winds
Mark A. Hutchison, Guillaume Laibe, Sarah T. Maddison
We model the behaviour of dust grains entrained by photoevaporation-driven winds from protoplanetary discs assuming a non-rotating, plane-parallel disc. We obtain an analytic expre…
