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…
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…
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…
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…
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…
