The protoplanetary disc around HD 169142: circumstellar or circumbinary?
P. P. Poblete, N. Cuello, S. Pérez +12
Stellar binaries represent a substantial fraction of stellar systems, especially among young stellar objects. Accordingly, binaries play an important role in setting the architectu…
High-resolution ALMA observations of V4046Sgr: a circumbinary disc with a thin ring
Rafael Martinez-Brunner, Simon Casassus, Sebastián Pérez +8
The nearby V4046 Sgr spectroscopic binary hosts a gas-rich disc known for its wide cavity and dusty ring. We present high resolution (20 mas or 1.4 au) ALMA observations of t…
Carbon monoxide gas produced by a giant impact in the inner region of a young system
Tajana Schneiderman, Luca Matrà, Alan P. Jackson +7
Models of terrestrial planet formation predict that the final stages of planetary assembly, lasting tens of millions of years beyond the dispersal of young protoplanetary disks, ar…
The formation of wide exoKuiper belts from migrating dust traps
E. Miller, S. Marino, S. M. Stammler +4
The question of what determines the width of Kuiper belt analogues (exoKuiper belts) is an open one. If solved, this understanding would provide valuable insights into the architec…
High resolution ALMA and HST images of q Eri: an asymmetric debris disc with an eccentric Jupiter
J. B. Lovell, S. Marino, M. C. Wyatt +10
We present \textit{ALMA} 1.3 mm and 0.86 mm observations of the nearby (17.34 pc) F9V star q1 Eri (HD 10647, HR 506). This system, with age Gyr, hosts a au ra…
Observability of the Vertical Shear Instability in protoplanetary disk CO kinematics
Marcelo Barraza-Alfaro, Mario Flock, Sebastian Marino +1
Context. Dynamical and turbulent motions of gas in a protoplanetary disk are crucial for their evolution and affect planet formation. Recent observations suggest weak turbulence in…
A detailed characterization of HR 8799's debris disk with ALMA in Band 7
Virginie Faramaz, Sebastian Marino, Mark Booth +8
The exoplanetary system of HR 8799 is one of the rare systems in which multiple planets have been directly imaged. Its architecture is strikingly similar to that of the Solar Syste…
Constraining planetesimal stirring: how sharp are debris disc edges?
Sebastian Marino
The dust production in debris discs by grinding collisions of planetesimals requires their orbits to be stirred. However, stirring levels remain largely unconstrained, and conseque…
Resolving Structure in the Debris Disk around HD 206893 with ALMA
Ava Nederlander, A. Meredith Hughes, Anna J. Fehr +7
Debris disks are tenuous, dusty belts surrounding main sequence stars generated by collisions between planetesimals. HD 206893 is one of only two stars known to host a directly ima…
