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 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…
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…
