The Exceptional Ring of buoyancy instability in stars
Armand Leclerc, Lucien Jezequel, Nicolas Perez +3
We reveal properties of global modes of linear buoyancy instability in stars, characterised by the celebrated Schwarzschild criterion, using non-Hermitian topology. We identify a r…
Dynamics of dust grains in turbulent molecular clouds. Conditions for decoupling and limits of different numerical implementations
Benoît Commerçon, Ugo Lebreuilly, Daniel J. Price +3
Dust grain dynamics in molecular clouds is regulated by its interplay with supersonic turbulent gas motions. The conditions under which dust grains decouple from the dynamics of ga…
On the origin of horseshoes in transitional discs
Enrico Ragusa, Giovanni Dipierro, Giuseppe Lodato +2
We investigate whether the rings, lopsided features and horseshoes observed at millimetre wavelengths in transitional discs can be explained by the dynamics of gas and dust at the…
Grand challenges in protoplanetary disc modelling
Thomas J. Haworth, John D. Ilee, Duncan H. Forgan +18
The Protoplanetary Discussions conference --- held in Edinburgh, UK, from 7th --11th March 2016 --- included several open sessions led by participants. This paper reports on the di…
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…
The marriage of gas and dust
Daniel Price, Guillaume Laibe
Dust-gas mixtures are the simplest example of a two fluid mixture. We show that when simulating such mixtures with particles or with particles coupled to grids a problem arises due…
