Dust and Gas Transport in Substructured Nonideal MHD Wind-Launching Disks with Embedded Planets
Chun-Yen Hsu, Zhi-Yun Li, Xiao Hu +2
Radial dust transport in protoplanetary disks is a key process shaping planet formation and disk chemistry. We investigate how this transport, along with gas transport, is regulate…
JCMT detection of HCN emission from 3I/ATLAS at 2.1 AU
Iain M. Coulson, Yi-Jehng Kuan, Steven B. Charnley +8
We report the detection of HCN () rotational emission from comet 3I/ATLAS at a heliocentric distance of 2.13 AU with the James Clerk Maxwell Telescope (JCMT). Observations w…
An MHD-based model for wind-driven disc-planet interactions
Michael Hammer, Min-Kai Lin
Hydrodynamic simulations of protoplanetary discs with planets typically assume that the disc is viscously driven, even though magnetic disc winds are now considered the primary dri…
Dust Growth in ALMA Rings: II. Dusty Rossby Wave Instability
Can Cui, Konstantin Gerbig, Ya-Ping Li +5
Annular substructures serve as ideal venues for planetesimal formation. In this series, we investigate the linear stage of dust growth within rings. The first paper examines the gl…
Convective Overstability in Radially Global Protoplanetary Disks. II. Impact on planetesimal formation
Marius Lehmann, Min-Kai Lin
The Convective Overstability (COS) is a hydrodynamic instability occurring in protoplanetary disk (PPD) regions with an adverse radial entropy gradient. It is a potential driver of…
Dust Concentration Via Coupled Vertical Settling and Radial Migration in Substructured Non-Ideal MHD Discs and Early Planet Formation
Chun-Yen Hsu, Zhi-Yun Li, Yisheng Tu +2
We investigate the dynamics of dust concentration in actively accreting, substructured, non-ideal MHD wind-launching disks using 2D and 3D simulations incorporating pressureless du…
Rossby Wave Instability and Substructure Formation in 3D Non-Ideal MHD Wind-Launching Disks
Chun-Yen Hsu, Zhi-Yun Li, Yisheng Tu +2
Rings and gaps are routinely observed in the dust continuum emission of protoplanetary discs (PPDs). How they form and evolve remains debated. Previous studies have demonstrated th…
Rossby wave instability in weakly ionized protoplanetary disks. I. azimuthal or vertical B-fields
Can Cui, Ashutosh Tripathi, Cong Yu +2
Rossby wave instability (RWI) is considered the underlying mechanism to crescent-shaped azimuthal asymmetries, discovered in (sub-)millimeter dust continuum of many protoplanetary…
Dust Dynamics in Hall-effected Protoplanetary Disks. I. Background Drift Hall Instability
Yinhao Wu, Min-Kai Lin, Can Cui +3
Recent studies have shown that the large-scale gas dynamics of protoplanetary disks (PPDs) are controlled by non-ideal magneto-hydrodynamics (MHD), but how this influences dust dyn…
Filament formation due to diffusive instabilities in dusty protoplanetary disks
Konstantin Gerbig, Min-Kai Lin, Marius Lehmann
We report the finding of a new, local diffusion instability in a protoplanetary disk, which can operate in a dust fluid, subject to mass diffusion, shear viscosity, and dust-gas dr…
