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…
Discs are born eccentric
Benoit Commerçon, Francesco Lovascio, Elliot Lynch +1
Recent observations have begun probing the early phases of disc formation, but little data yet exists on disc structure and morphology of Class 0 objects. Using simulations, we are…
Local Spherical Collapsing Box in Athena++: Numerical Implementation and Benchmark Tests
Ziyan Xu, Elliot M. Lynch, Guillaume Laibe
We implement a local model for a spherical collapsing/expanding gas cloud into the Athena++ magnetohydrodynamic code. This local model consists of a Cartesian periodic box with tim…
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…
