Disk dissipation, giant planet formation and star-formation-rate fluctuations in the past three-million-year history of Gould's Belt
Mingchao Liu, Jinhua He, Jixing Ge +3
Although episodic star formation (SF) had been suggested for nearby SF regions, a panoramic view to the latest episodic SF history in the solar neighborhood is still missing. By un…
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.…
The ALMA-QUARKS survey: Investigating Thermal Feedback of Massive Protostars in Hot Molecular Cores
Dezhao Meng, Tie Liu, Jarken Esimbek +33
We identify a sample of 83 spatially resolved hot molecular cores (HMCs) in the QUARKS survey, aiming at investigating thermal feedback from massive stars. Using CHCN\,(12--11)…
GGCHEMPY: A pure Python-based gas-grain chemical code for efficient simulation of interstellar chemistry
Jixing Ge
In this paper, we present a new gas-grain chemical code for interstellar clouds written in pure Python (GGCHEMPY). By combining with the high-performance Python compiler Numba, GGC…
Can near-to-mid infrared spectral energy distribution quantitatively trace protoplanetary disk evolution?
Mingchao Liu, Jinhua He, Zhen Guo +2
Infrared (IR) spectral energy distribution (SED) is the major tracer of protoplanetary disks. It was recently proposed to use the near-to-mid IR (or K-24) SED slope defined be…
Early-stage star forming cloud cores in GLIMPSE Extended Green Objects (EGOs) as traced by organic species
Jixing Ge, Jinhua He, Xi Chen +1
In order to investigate the physical and chemical properties of massive star forming cores in early stages, we analyse the excitation and abundance of four organic species, CH3OH,…
