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…
Angular Momentum of Planet-Forming Disks: Implications for Infall Driven Misalignments
Aashish Gupta, Cristiano Longarini, L. Ilsedore Cleeves +5
Context. A significant fraction (>30%) of planet-forming disks and planetary are misaligned with respect to the rotational axis of their host stars, yet the dominant mechanism resp…
Modeling YSO Jets in 3D III: Dependence of Accretion and Jet Properties on Stellar Magnetospheric Field Strength and Rotation
Yisheng Tu, Zhi-Yun Li, Zhaohuan Zhu +1
Observations of Young Stellar Objects (YSOs) systems reveal a wide diversity of jet properties, from well-collimated bipolar jets to uni-polar jets and systems with no detectable j…
A New Method of Measuring Magnetic Field Strength in Highly Structured Protostellar Envelopes
Yisheng Tu, Xiaoyuan Yang, Zhi-Yun Li
Magnetic fields play a fundamental role in protostellar collapse and disk formation, yet direct measurements of magnetic field strength in deeply embedded protostellar envelopes re…
MHD Simulations of Strongly Magnetized HII Region Evolution: Evidence for Ionized Gas Filamentation
Samuel Crowe, Yisheng Tu, Zhi-Yun Li +2
Recent JWST observations of HII regions in the Central Molecular Zone have shown a highly filamentary morphology distinct from HII regions in other parts of the galaxy. We present…
A tale of three tails: A misaligned streamer and mysterious structures around [BHB2007]1
Aashish Gupta, Antonio S. Hales, L. Ilsedore Cleeves +8
Recent discoveries of streamer-like structures around protostellar sources challenge the traditional picture of isolated, axisymmetric star formation. Here, we present new ALMA obs…
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…
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…
Modeling YSO Jets in 3D I: Highly Variable Asymmetric Magnetic Pressure-Driven Jets in the Polar Cavity from Toroidal Fields Generated by Inner Disk Accretion
Yisheng Tu, Zhi-Yun Li, Zhaohuan Zhu +2
Jets and outflows are commonly observed in young stellar objects (YSOs), yet their origins remain debated. Using 3D non-ideal magnetohydrodynamic (MHD) simulations of a circumstell…
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…
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 (…
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…
Fragmentation of Dense Rotation-Dominated Structures Fed by Collapsing Gravomagneto-Sheetlets and Origin of Misaligned 100 au-Scale Binaries and Multiple Systems
Yisheng Tu, Zhi-Yun Li, Zhaohuan Zhu +1
The majority of stars are in binary/multiple systems. How such systems form in turbulent, magnetized cores of molecular clouds in the presence of non-ideal MHD effects remains rela…
The fastest components in stellar jets
Hans Moritz Günther, Catherine Espaillat, Kevin France +8
Young stars accrete mass from a circumstellar disk, but at the same time disk and star eject outflows and jets. These outflows have an onion-like structure where the innermost and…
