INvestigations of massive Filaments ANd sTar formation (INFANT). I. Core Identification and Core Mass Function
Yu Cheng, Xing Lu, Patricio Sanhueza +16
Filamentary structures are ubiquitously found in high-mass star-forming clouds. To investigate the relationship between filaments and star formation, we carry out the INFANT (INves…
The ALMA Survey of 70 μm Dark High-mass Clumps in Early Stages (ASHES). VI. The core-scale CO-depletion
Giovanni Sabatini, Stefano Bovino, Patricio Sanhueza +11
Studying the physical and chemical properties of cold and dense molecular clouds is crucial for the understanding of how stars form. Under the typical conditions of infrared dark c…
Chemical and Physical Characterization of the Isolated Protostellar Source CB68: FAUST. IV
Muneaki Imai, Yoko Oya, Brian Svoboda +1
Chemical diversity of low-mass protostellar sources has so far been recognized, and environmental effects are invoked as its origin. In this context, observations of isolated proto…
ALMA observations of NGC 6334S. II. Subsonic and Transonic Narrow Filaments in a High-mass Star Formation Cloud
Shanghuo Li, Patricio Sanhueza, Chang Won Lee +22
We present a study of narrow filaments toward a massive infrared dark cloud, NGC 6334S, using the Atacama Large Millimeter/submillimeter Array (ALMA). Thirteen gas filaments are id…
The ALMA Survey of 70 m Dark High-mass Clumps in Early Stages (ASHES). IV. Star formation signatures in G023.477
Kaho Morii, Patricio Sanhueza, Fumitaka Nakamura +15
With a mass of 1000 and a surface density of 0.5 g cm, G023.477+0.114 also known as IRDC 18310-4 is an infrared dark cloud (IRDC) that has the potentia…
Molecular Cloud Cores with High Deuterium Fractions: Nobeyama Mapping Survey
Ken'ichi Tatematsu, Gwanjeong Kim, Tie Liu +35
We present the results of on-the-fly mapping observations of 44 fields containing 107 SCUBA-2 cores in the emission lines of molecules, NH, HCN, and CCS at 8294 GHz…
Magnetic fields at the onset of high-mass star formation
H. Beuther, J. Soler, W. Vlemmings +9
Context: The importance of magnetic fields at the onset of star formation related to the early fragmentation and collapse processes is largely unexplored today. Aims: We want to un…
Filamentary Fragmentation and Accretion in High-Mass Star-Forming Molecular Clouds
Xing Lu, Qizhou Zhang, Hauyu Baobab Liu +7
Filamentary structures are ubiquitous in high-mass star-forming molecular clouds. Their relation with high-mass star formation is still to be understood. Here we report interferome…
The TOP-SCOPE survey of Planck Galactic Cold Clumps: Survey overview and results of an exemplar source, PGCC G26.53+0.17
Tie Liu, Kee-Tae Kim, Mika Juvela +11
The low dust temperatures (<14 K) of Planck Galactic Cold Clumps (PGCCs) make them ideal targets to probe the initial conditions and very early phase of star formation. TOP-SCOPE i…
Inferring the evolutionary stages of the internal structures of NGC 7538 S and IRS1 from chemistry
S. Feng, H. Beuther, D. Semenov +4
To unambiguously diagnose the detailed physical mechanisms and the evolutionary status of high-mass star-forming regions (HMSFRs), we have performed 0.4" ( AU) resolution…
Outflow detection in a 70 m dark high-mass core
S. Feng, H. Beuther, Q. Zhang +4
We present observations towards a high-mass (), low luminosity () m dark molecular core G 28.34 S-A at 3.4 mm, using the IRAM 30…
Are Infrared Dark Clouds Really Quiescent?
S. Feng, H. Beuther, Q. Zhang +4
The dense, cold regions where high-mass stars form are poorly characterised, yet they represent an ideal opportunity to learn more about the initial conditions of high-mass star fo…
Hierarchical fragmentation and collapse signatures in a high-mass starless region
H. Beuther, Th. Henning, H. Linz +6
Aims: Understanding the fragmentation and collapse properties of the dense gas during the onset of high-mass star formation. Methods: We observed the massive (~800M_sun) starless g…
Resolving the chemical substructure of Orion-KL
S. Feng, H. Beuther, T. Henning +3
The Kleinmann-Low nebula in Orion (Orion-KL) is the nearest example of a high-mass star-forming environment. For the first time, we complemented 1.3 mm Submillimeter Array (SMA) in…
