Consistent dust and gas models for protoplanetary disks III. Models for selected objects from the FP7 DIANA project
P. Woitke, I. Kamp, S. Antonellini +17
The European FP7 project DIANA has performed a coherent analysis of a large set of observations from protoplanetary disks by means of thermo-chemical disk models. The collected dat…
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…
A search for accreting young companions embedded in circumstellar disks: High-contrast H imaging with VLT/SPHERE
G. Cugno, S. P. Quanz, S. Hunziker +37
Aims: We want to detect and quantify observables related to accretion processes occurring locally in circumstellar disks, which could be attributed to young forming planets. We foc…
Super-Earths in the TW Hya disc
Daniel Mentiplay, Daniel J. Price, Christophe Pinte
We test the hypothesis that the sub-millimetre thermal emission and scattered light gaps seen in recent observations of TW Hya are caused by planet-disc interactions. We perform gl…
F.S.I.: Flyby Scene Investigation
Nicolás Cuello, Giovanni Dipierro, Daniel Mentiplay +7
We present a methodology to interpret observations of protoplanetary discs where a flyby, also called a tidal encounter, is suspected. In case of a flyby, protoplanetary discs can…
Submillimetre dust polarisation and opacity in the HD163296 protoplanetary ring system
W. R. F. Dent, C. Pinte, P. C. Cortes +4
We present ALMA images of the sub-mm continuum polarisation and spectral index of the protoplanetary ringed disk HD163296. The polarisation fraction at 870μm is measured to be ~0.9…
