Conditions for planetesimal formation via the streaming instability persist under turbulence driven by magnetorotational instability
Linn E. J. Eriksson, Ziyan Xu, Jeonghoon Lim +3
Strong dust clumping by streaming instability (SI) is the leading proposed mechanism for forming planetesimals, the building blocks of terrestrial planets and giant-planet cores. T…
Local Spherical Collapsing Box in Athena++: Numerical Implementation and Benchmark Tests
Ziyan Xu, Elliot M. Lynch, Guillaume Laibe
We implement a local model for a spherical collapsing/expanding gas cloud into the Athena++ magnetohydrodynamic code. This local model consists of a Cartesian periodic box with tim…
Turbulent Dust-trapping Rings as Efficient Sites for Planetesimal Formation
Ziyan Xu, Xue-Ning Bai
Recent observations of protoplanetary disks (PPDs) in the sub-mm have revealed the ubiquity of annular substructures, indicative of pebble-sized dust particles trapped in turbulent…
The ODYSSEUS Survey. Motivation and First Results: Accretion, Ejection, and Disk Irradiation of CVSO 109
C. C. Espaillat, G. J. Herczeg, T. Thanathibodee +59
The Hubble UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Director's Discretionary Program of low-mass pre-main-sequence stars, coupled with forthcoming data fro…
Dust Settling and Clumping in MRI Turbulent Outer Protoplanetary Disks
Ziyan Xu, Xue-Ning Bai
Planetesimal formation is a crucial yet poorly understood process in planet formation. It is widely believed that planetesimal formation is the outcome of dust clumping by the stre…
Probing Protoplanetary Disk Winds with C II Absorption
Ziyan Xu, Gregory J. Herczeg, Christopher M. Johns-Krull +1
We present an analysis of wind absorption in the C II doublet towards 40 classical T Tauri stars with archival far-ultraviolet (FUV) spectra obtained by the Hubble Space Te…
The JCMT Transient Survey: Four Year Summary of Monitoring the Submillimeter Variability of Protostars
Yong-Hee Lee, Doug Johnstone, Jeong-Eun Lee +49
We present the four-year survey results of monthly submillimeter monitoring of eight nearby (pc) star-forming regions by the JCMT Transient Survey. We apply the Lomb-Scargl…
Pebble Accretion in Turbulent Protoplanetary Disks
Ziyan Xu, Xue-Ning Bai, Ruth Murray-Clay
It has been realized in recent years that the accretion of pebble-sized dust particles onto planetary cores is an important mode of core growth, which enables the formation of gian…
