Mapping the merging zone of late infall in the AB Aur planet-forming system
Jessica Speedie, Ruobing Dong, Richard Teague +10
Late infall events challenge the traditional view that planet formation occurs without external influence. Here we present deep ALMA CO and SO observ…
Gravitational instability in a planet-forming disk
Jessica Speedie, Ruobing Dong, Cassandra Hall +7
The canonical theory for planet formation in circumstellar disks proposes that planets are grown from initially much smaller seeds. The long-considered alternative theory proposes…
Weighing protoplanetary discs with kinematics: physical model, method and benchmark
Benedetta Veronesi, Cristiano Longarini, Giuseppe Lodato +4
The mass of protoplanetary discs sets the amount of material available for planet formation, determines the level of coupling between gas and dust, and possibly sets gravitational…
Dynamical mass measurements of two protoplanetary discs
G. Lodato, L. Rampinelli, E. Viscardi +8
ALMA observations of line emission from planet forming discs have demonstrated to be an excellent tool to probe the internal disc kinematics, often revealing subtle effects related…
Investigating Protoplanetary Disk Cooling through Kinematics: Analytical GI Wiggle
Cristiano Longarini, Giuseppe Lodato, Claudia Toci +4
It is likely that young protostellar disks undergo a self-gravitating phase. Such systems are characterized by the presence of a spiral pattern that can be either in a quasi-steady…
Constraining protoplanetary disc mass using the GI wiggle
J. P. Terry, C. Hall, Cristiano Longarini +5
Exoplanets form in protoplanetary accretion discs. The total protoplanetary disc mass is the most fundamental parameter, since it sets the mass budget for planet formation. Althoug…
A dynamical measurement of the disk mass in Elias 2-27
Benedetta Veronesi, Teresa Paneque-Carreno, Giuseppe Lodato +4
Recent multi-wavelength ALMA observations of the protoplanetary disk orbiting around Elias 2-27 revealed a two armed spiral structure. The observed morphology together with the you…
Spiral Arms and a Massive Dust Disk with non-Keplerian Kinematics: Possible Evidence for Gravitational Instability in the Disk of Elias 2-27
T. Paneque-Carreño, L. M. Perez, M. Benisty +16
To determine the origin of the spiral structure observed in the dust continuum emission of Elias 2-27 we analyze multi-wavelength continuum ALMA data with a resolution of 0.2…
Is the gap in the DS Tau disc hiding a planet?
Benedetta Veronesi, Enrico Ragusa, Giuseppe Lodato +6
Recent mm-wavelength surveys performed with the Atacama Large Millimeter Array (ALMA) have revealed protoplanetary discs characterized by rings and gaps. A possible explanation for…
Multi-wavelength observations of protoplanetary discs as a proxy for the gas disc mass
B. Veronesi, G. Lodato, G. Dipierro +3
Recent observations of protoplanetary discs reveal disc substructures potentially caused by embedded planets. We investigate how the gas surface density in discs changes the observ…
Enforcing dust mass conservation in 3D simulations of tightly-coupled grains with the Phantom SPH code
Giulia Ballabio, Giovanni Dipierro, Benedetta Veronesi +4
We describe a new implementation of the one-fluid method in the SPH code Phantom to simulate the dynamics of dust grains in gas protoplanetary discs. We revise and extend previousl…
