Formation of a Protostellar Multiple System via Rotational Fragmentation
Tie Liu, Qiuyi Luo, Siju Zhang +1
We present a multi-scale analysis of the dense core G205.46-14.56-N2 and its host filament G205.46-14.56 using ALMA, Herschel, JCMT, and PMO observations. The filament exhibits a h…
Evolution of starless cores in massive clumps seen by the ALMA ASHES and QUARKS surveys
Dongting Yang, Hong-li Liu, Sheng-li Qin +28
We present a systematic comparative analysis of 324 starless cores in early-phase infrared-dark clouds (IRDCs; ASHES survey) and evolved-phase infrared-bright clouds (IRBCs; QUARKS…
Tracking Protostellar Variability in Massive Protoclusters with ALMA: I. Insights from QUARKS and MaMMOtH
Yuhan Yang, Tie Liu, Sheng-Yuan Liu +22
Millimeter/submillimeter variability is often attributed to dynamical disk-mediated accretion, yet detection is limited to low-mass protostars in nearby clouds. Recent observations…
Core mass function in view of fractal and turbulent filaments and fibers
Xunchuan Liu, Tie Liu, Xiaofeng Mai +5
We propose that the core mass function (CMF) can be driven by filament fragmentation. To model a star-forming system of filaments and fibers, we develop a fractal and turbulent tre…
ATOMS: ALMA three-millimeter observations of massive star-forming regions -- XVIII. On the origin and evolution of dense gas fragments in molecular shells of compact HII regions
Siju Zhang, Tie Liu, Ke Wang +16
Fragmentation and evolution for the molecular shells of the compact HII regions are less explored compared to their evolved counterparts. We map nine compact HII regions with a typ…
JCMT 850 $\micron$ continuum observations of density structures in the G35 molecular complex
Xianjin Shen, Hong-Li Liu, Zhiyuan Ren +32
Filaments are believed to play a key role in high-mass star formation. We present a systematic study of the filaments and their hosting clumps in the G35 molecular complex using JC…
The ALMA-QUARKS survey: -- I. Survey description and data reduction
Xunchuan Liu, Tie Liu, Lei Zhu +31
This paper presents an overview of the QUARKS survey, which stands for `Querying Underlying mechanisms of massive star formation with ALMA-Resolved gas Kinematics and Structures'.…
Evidence of high-mass star formation through multi-scale mass accretion in hub-filament-system clouds
Hong-Li Liu, Anandmayee Tej, Tie Liu +30
We present a statistical study of a sample of 17 hub-filament-system (HFS) clouds of high-mass star formation using high-angular resolution (1-2 arcsecond) ALMA 1.3mm and 3mm…
Fragmentation of the High-mass "Starless'' Core G10.21-0.31: a Coherent Evolutionary Picture for Star Formation
Wenyu Jiao, Ke Wang, Thushara G. S. Pillai +3
G10.21-0.31 is a 70 m-dark high-mass starless core ( within pc) identified in , , and APEX continuum surveys, and is beli…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- XV. Steady Accretion from Global Collapse to Core Feeding in Massive Hub-filament System SDC335
Feng-Wei Xu, Ke Wang, Tie Liu +37
We present ALMA Band-3/7 observations towards "the Heart" of a massive hub-filament system (HFS) SDC335, to investigate its fragmentation and accretion. At a resolution of $\sim0.0…
Formation of hub-filament structure triggered by cloud-cloud collision in W33 complex
Jian-Wen Zhou, Shanghuo Li, Hong-Li Liu +6
Hub-filament systems are suggested to be birth cradles of high-mass stars and clusters, but the formation of hub-filament structure is still unclear. Using the survey data FUGIN $^…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- XI. From inflow to infall in hub-filament systems
Jian-Wen Zhou, Tie Liu, Neal J. Evans +37
We investigate the presence of hub-filament systems in a large sample of 146 active proto-clusters, using HCO J=1-0 molecular line data obtained from the ATOMS survey.…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): How do dense core properties affect the multiplicity of protostars?
Qiuyi Luo, Tie Liu, Kenichi Tatematsu +34
During the transition phase from a prestellar to a protostellar cloud core, one or several protostars can form within a single gas core. The detailed physical processes of this tra…
