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…
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…
Probing the eccentricity in protostellar discs -- Modeling kinematics and morphologies
Enrico Ragusa, Elliot Lynch, Guillaume Laibe +2
Protostellar discs are mostly modelled as circular structures of gas and dust orbiting a protostar. However, a number of physical mechanisms, e.g. the presence of a (sub)stellar co…
