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…
Modeling YSO Jets in 3D II: Accretion-Fed, Star-Anchored Poynting Jets in the Low-Density Polar Cavity Powered by Disk-Magnetosphere Interaction
Yisheng Tu, Zhi-Yun Li, Zhaohuan Zhu +2
The origin of jets in young stellar objects (YSOs) remains a subject of active investigation. We present a 3D magnetohydrodynamic simulation of jet launching in YSOs, focusing on t…
YSO Jets Magnetocentrifugally Driven by Reconnecting Atmospheric Avalanche Accretion Streams Above Inner Circumstellar Disks
Yisheng Tu, Zhi-Yun Li, Zhaohuan Zhu +2
Fast, collimated jets are ubiquitous features of young stellar objects (YSOs). They are generally thought to be powered by disk accretion, but the details are debated. Through 2D (…
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…
3D Gap Opening in Non-Ideal MHD Protoplanetary Disks: Asymmetric Accretion, Meridional Vortices, and Observational Signatures
Xiao Hu, Zhi-Yun Li, Jaehan Bae +1
Recent high-angular resolution ALMA observations have revealed rich information about protoplanetary disks, including ubiquitous substructures and three-dimensional gas kinematics…
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…
