Revisiting the picture of circumbinary disc truncation

Enrico Ragusa, Elliot Lynch, Guillaume Laibe +1

Circumbinary discs are observed to develop central cavities carved by the gravitational influence of the binary. Analytical estimates of cavity sizes predict truncation at $\sim 2…

Rescaling Transforms for Local Models of Spherical Flows

Elliot M. Lynch, Guillaume Laibe

Previously we developed a local model for a spherically contracting/expanding gas cloud that can be used to study turbulence and small scale instabilities in such flows. In this wo…

Numerical Insights into Disk Accretion, Eccentricity, and Kinematics in the Class 0 phase

Adnan Ali Ahmad, Benoît Commerçon, Elliot Lynch +4

The formation and early evolution of protoplanetary disks are governed by a wide variety of physical processes during a gravitational collapse. Observations have begun probing disk…

Radial modes of pressure bumps and dips in astrophysical discs

Armand Leclerc, Guillaume Laibe, Elliot Lynch +1

This study investigates the signatures of pressure extrema on global oscillations in discs. To this end, we use the framework of wave topology to establish a generalised local disp…

Developing a Non-Newtonian Fluid Model for Dust, for Application to Astrophysical Flows

Elliot M. Lynch, Guillaume Laibe

In the astrophysics community it is common practice to model collisionless dust, entrained in a gas flow, as a pressureless fluid. However a pressureless fluid is fundamentally dif…
