Observing planetesimal formation under streaming instability in the rings of HD 163296
Francesco Zagaria, Cathie J. Clarke, Richard A. Booth +2
We introduce a new technique to determine the gas turbulence and surface density in bright disc rings, under the assumption that dust growth is limited by turbulent fragmentation a…
Synthetic populations of protoplanetary disks. Impact of magnetic fields and radiative transfer
U. Lebreuilly, P. Hennebelle, T. Colman +10
Protostellar disks are the product of angular momentum conservation during the protostellar collapse. Understanding their formation is crucial because they are the birthplace of pl…
Dual-Band Observations of the Asymmetric Ring around CIDA 9A: Dead or Alive?
Daniel Harsono, Feng Long, Paola Pinilla +9
While the most exciting explanation of the observed dust asymmetries in protoplanetary disks is the presence of protoplanets, other mechanisms can also form the dust features. This…
The population of young low-mass stars in Trumpler 14
Dominika Itrich, Leonardo Testi, Giacomo Beccari +8
Massive star-forming regions are thought to be the most common birth environments in the Galaxy and the only birth places of very massive stars. Their presence in the stellar clust…
The time evolution of in protoplanetary discs as a way to disentangle between viscosity and MHD winds
Alice Somigliana, Leonardo Testi, Giovanni Rosotti +5
As the classic viscous paradigm for protoplanetary disk accretion is challenged by the observational evidence of low turbulence, the alternative scenario of MHD disk winds is being…
Radio multiwavelength analysis of the compact disk CX Tau: Presence of strong free-free variability or anomalous microwave emission
Pietro Curone, Leonardo Testi, Enrique Macias +8
Protoplanetary disks emit radiation across a broad range of wavelengths, requiring a multiwavelength approach to fully understand their physical mechanisms and how they form planet…
Constraining turbulence in protoplanetary discs using the gap contrast: an application to the DSHARP sample
E. Pizzati, G. P. Rosotti, B. Tabone
Constraining the strength of gas turbulence in protoplanetary discs is an open problem that has relevant implications for the physics of gas accretion and planet formation. In this…
How large is a disk -- what do protoplanetary disk gas sizes really mean?
Leon Trapman, Giovanni Rosotti, Ke Zhang +1
It remains unclear what mechanism is driving the evolution of protoplanetary disks. Direct detection of the main candidates, either turbulence driven by magnetorotational instabili…
The Effect of Dust Evolution and Traps on Inner Disk Water Enrichment
Anusha Kalyaan, Paola Pinilla, Sebastiaan Krijt +6
Substructures in protoplanetary disks can act as dust traps that shape the radial distribution of pebbles. By blocking the passage of pebbles, the presence of gaps in disks may hav…
JWST reveals excess cool water near the snowline in compact disks, consistent with pebble drift
Andrea Banzatti, Klaus M. Pontoppidan, John Carr +19
Previous analyses of mid-infrared water spectra from young protoplanetary disks observed with the Spitzer-IRS found an anti-correlation between water luminosity and the millimeter…
The distribution of accretion rates as a diagnostic of protoplanetary disc evolution
R. Alexander, G. Rosotti, P. J. Armitage +3
We show that the distribution of observed accretion rates is a powerful diagnostic of protoplanetary disc physics. Accretion due to turbulent ("viscous") transport of angular momen…
Distinguishing Magnetized Disc Winds from Turbulent Viscosity through Substructure Morphology in Planet-forming Discs
Yinhao Wu, Yi-Xian Chen, Haochang Jiang +5
The traditional paradigm of viscosity-dominated evolution of protoplanetary discs has been recently challenged by magnetized disc winds. However, distinguishing wind-driven and tur…
The Disc Miner II: Revealing Gas substructures and Kinematic signatures from Planet-disc interaction through line profile analysis
Andres F. Izquierdo, Leonardo Testi, Stefano Facchini +4
[Abridged] The aim of this work is to identify potential signatures from planet-disc interaction in the circumstellar discs around MWC 480, HD 163296, AS 209, IM Lup, and GM Aur, t…
Empirical constraints on turbulence in proto-planetary discs
Giovanni P. Rosotti
Proto-planetary discs, the birth environment of planets, are an example of a structure commonly found in astrophysics, accretion discs. Identifying the mechanism responsible for ac…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): Diverse outcomes of binary-disk interactions
Yapeng Zhang, Christian Ginski, Jane Huang +15
Circumstellar disks do not evolve in isolation, as about half of solar-type stars were born in binary or multiple systems. Resolving disks in binary systems provides the opportunit…
