High resolution observations of molecular emission lines toward the CI Tau proto-planetary disc: planet-carved gaps or shadowing?
Giovanni P. Rosotti, John D. Ilee, Stefano Facchini +4
Recent observations have revealed that most proto-planetary discs show a pattern of bright rings and dark gaps. However, most of the high-resolution observations have focused only…
Rapid CO gas dispersal from NO Lup's class III circumstellar disc
J. B. Lovell, G. M. Kennedy, S. Marino +9
We observed the K7 class III star NO Lup in an ALMA survey of the 1-3 Myr Lupus association and detected circumstellar dust and CO gas. Here we show that the J = 3-2 CO emission is…
ALMA Survey of Lupus Class III Stars: Early Planetesimal Belt Formation and Rapid Disk Dispersal
J. B. Lovell, M. C. Wyatt, M. Ansdell +9
Class III stars are those in star forming regions without large non-photospheric infrared emission, suggesting recent dispersal of their protoplanetary disks. We observed 30 class…
Multi-wavelength continuum sizes of protoplanetary discs: scaling relations and implications for grain growth and radial drift
Marco Tazzari, Cathie J. Clarke, Leonardo Testi +5
We analyse spatially resolved ALMA observations at 0.9, 1.3, and 3.1 mm for the 26 brightest protoplanetary discs in the Lupus star-forming region. We characterise the discs multi-…
Dust dynamics in planet-driven spirals
Ardjan Sturm, Giovanni Rosotti, Carsten Dominik
Context. Protoplanetary disks are known to host spiral features that are observed in scattered light, ALMA continuum and more recently in CO gas emission and gas dynamics. It is ho…
Visualizing the Kinematics of Planet Formation
Disk Dynamics Collaboration, Philip J. Armitage, Jaehan Bae +23
A stunning range of substructures in the dust of protoplanetary disks is routinely observed across a range of wavelengths. These gaps, rings and spirals are highly indicative of a…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): A close low mass companion to ET Cha
C. Ginski, F. Ménard, Ch. Rab +25
To understand the formation of planetary systems, one needs to understand the initial conditions of planet formation, i.e. the young gas-rich planet forming disks. Spatially resolv…
ISO-ChaI 52: a weakly-accreting young stellar object with a dipper light curve
A. Frasca, C. F. Manara, J. M. Alcalá +6
We report on the discovery of periodic dips in the multiband lightcurve of ISO-ChaI 52, a young stellar object in the Chamaeleon I dark cloud. This is one among the peculiar object…
Dust masses of young disks: constraining the initial solid reservoir for planet formation
Łukasz Tychoniec, Carlo F. Manara, Giovanni P. Rosotti +7
In recent years evidence has been building that planet formation starts early, in the first 0.5 Myr. Studying the dust masses available in young disks enables understanding…
Frankenstein: Protoplanetary disc brightness profile reconstruction at sub-beam resolution with a rapid Gaussian process
Jeff Jennings, Richard A. Booth, Marco Tazzari +2
Interferometric observations of the mm dust distribution in protoplanetary discs are now showing a ubiquity of annular gap and ring substructures. Their identification and accurate…
Observed sizes of planet-forming disks trace viscous evolution
L. Trapman, G. Rosotti, A. D. Bosman +2
The evolution of protoplanetary disks is dominated by the conservation of angular momentum, where the accretion of material onto the central star is driven by viscous expansion of…
X-Shooter survey of disk accretion in Upper Scorpius I. Very high accretion rates at age>5 Myr
C. F. Manara, A. Natta, G. P. Rosotti +14
Determining the mechanisms that drive the evolution of protoplanetary disks is a necessary step to understand how planets form. Here we measured the mass accretion rate for young s…
The efficiency of dust trapping in ringed proto-planetary discs
Giovanni P. Rosotti, Richard Teague, Cornelis Dullemond +2
When imaged at high-resolution, many proto-planetary discs show gaps and rings in their dust sub-mm continuum emission profile. These structures are widely considered to originate…
The Bardeen-Petterson effect in accreting supermassive black-hole binaries: a systematic approach
Davide Gerosa, Giovanni Rosotti, Riccardo Barbieri
Disc-driven migration is a key evolutionary stage of supermassive black-hole binaries hosted in gas-rich galaxies. Besides promoting the inspiral, viscous interactions tend to alig…
Planet gap opening across stellar masses
Catriona A. Sinclair, Giovanni P. Rosotti, Attila Juhasz +1
Annular structures in proto-planetary discs, such as gaps and rings, are now ubiquitously found by high-resolution ALMA observations. Under the hypothesis that they are opened by p…
Detectability of embedded protoplanets from hydrodynamical simulations
E. Sanchis, G. Picogna, B. Ercolano +2
We predict magnitudes for young planets embedded in transition discs, still affected by extinction due to material in the disc. We focus on Jupiter-size planets at a late stage of…
