A kinematic excess in the annular gap and gas depleted cavity in the disc around HD 169142
Himanshi Garg, Christophe Pinte, Iain Hammond +6
We present ALMA band 6 images of the 12CO, 13CO and C18O J=2-1 line emissions for the circumstellar disc around HD 169142, at ~8 au spatial resolution. We resolve a central gas dep…
Long live the disk: lifetimes of protoplanetary disks in hierarchical triple star systems and a possible explanation for HD 98800 B
María Paula Ronco, Octavio M. Guilera, Jorge Cuadra +5
The gas dissipation from a protoplanetary disk is one of the key processes affecting planet formation, and it is widely accepted that it happens on timescales of a few million year…
Fomalhaut b could be massive and sculpting the narrow, eccentric debris disc, if in mean-motion resonance with it
Tim D. Pearce, Hervé Beust, Virginie Faramaz +4
The star Fomalhaut hosts a narrow, eccentric debris disc, plus a highly eccentric companion Fomalhaut b. It is often argued that Fomalhaut b cannot have significant mass, otherwise…
Binary-induced spiral arms inside the disc cavity of AB Aurigae
Pedro P. Poblete, Josh Calcino, Nicolás Cuello +5
In this work we demonstrate that the inner spiral structure observed in AB Aurigae can be created by a binary star orbiting inside the dust cavity. We find that a companion with a…
Dusty clumps in circumbinary discs
Pedro P. Poblete, Nicolás Cuello, Jorge Cuadra
Recent observations have revealed that protoplanetary discs often exhibit cavities and azimuthal asymmetries such as dust traps and clumps. The presence of a stellar binary system…
Flybys in protoplanetary discs: I. Gas and dust dynamics
Nicolás Cuello, Giovanni Dipierro, Daniel Mentiplay +7
We present 3D smoothed particle hydrodynamics simulations of protoplanetary discs undergoing a flyby by a stellar perturber on a parabolic orbit lying in a plane inclined relative…
