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…
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…
Observational Signatures of Disk Winds in Protoplanetary Disks: Differentiating Magnetized and Photoevaporative Outflows With Fully Coupled Thermochemistry
Xiao Hu, Jaehan Bae, Zhaohuan Zhu +1
Magnetized winds and photoevaporative winds are critical in shaping protoplanetary disk evolution. Using 2D axisymmetric (magneto-)hydrodynamic simulations with Athena++ implementi…
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…
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…
Gap Opening in Protoplanetary Disks: Gas Dynamics from Global Non-ideal MHD Simulations with Consistent Thermochemistry
Xiao Hu, Zhi-Yun Li, Lile Wang +2
Recent high angular resolution ALMA observations have revealed numerous gaps in protoplanetary disks. A popular interpretation has been that planets open them. Most previous invest…
Formation of Dust Rings and Gaps in Non-ideal MHD Disks Through Meridional Gas Flows
Xiao Hu, Zhi-Yun Li, Zhaohuan Zhu +1
Rings and gaps are commonly observed in the dust continuum emission of young stellar disks. Previous studies have shown that substructures naturally develop in the weakly ionized g…
Inside-Out Planet Formation. VII. Astrochemical Models of Protoplanetary Disks and Implications for Planetary Compositions
Arturo Cevallos Soto, Jonathan C. Tan, Xiao Hu +2
Inside-Out Planet Formation (IOPF) proposes that the abundant systems of close-in Super-Earths and Mini-Neptunes form in situ at the pressure maximum associated with the Dead Zone…
Self-consistent ring model in protoplanetary disks: temperature dips and substructure formation
Shangjia Zhang, Xiao Hu, Zhaohuan Zhu +1
Rings and gaps are ubiquitous in protoplanetary disks. Larger dust grains will concentrate in gaseous rings more compactly due to stronger aerodynamic drag. However, the effects of…
A Tale of Two Grains: impact of grain size on ring formation via nonideal MHD processes
Xiao Hu, Lile Wang, Satoshi Okuzumi +1
Substructures in PPDs, whose ubiquity was unveiled by recent ALMA observations, are widely discussed regarding their possible origins. We carry out global full magnetohydrodynamic…
Non-ideal MHD simulation of HL Tau disk: formation of rings
Xiao Hu, Zhaohuan Zhu, Satoshi Okuzumi +4
Recent high resolution observations unveil ring structures in circumstellar disks. The origin of these rings has been widely investigated under various theoretical scenarios. In th…
Inside-Out Planet Formation. IV. Pebble Evolution and Planet Formation Timescales
Xiao Hu, Jonathan C. Tan, Zhaohuan Zhu +4
Systems with tightly-packed inner planets (STIPs) are very common. Chatterjee & Tan proposed Inside-Out Planet Formation (IOPF), an in situ formation theory, to explain these plane…
An Overview of Inside-Out Planet Formation
Jonathan C. Tan, Sourav Chatterjee, Xiao Hu +2
The Kepler-discovered Systems with Tightly-packed Inner Planets (STIPs), typically with several planets of Earth to super-Earth masses on well-aligned, sub-AU orbits may host the m…
Inside-Out Planet Formation. III. Planet-disk interaction at the dead zone inner boundary
Xiao Hu, Zhaohuan Zhu, Jonathan C. Tan +1
The Kepler mission has discovered more than 4000 exoplanet candidates. Many are in systems with tightly packed inner planets. Inside-Out Planet Formation (IOPF) has been proposed t…
Pebble Delivery for Inside-Out Planet Formation
Xiao Hu, Jonathan C. Tan, Sourav Chatterjee
Inside-Out Planet Formation (IOPF; Chatterjee & Tan 2014, hereafter CT14) is a scenario for sequential in situ planet formation at the pressure traps of retreating dead zone inner…
