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…
