ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): A forming quadruple system with continuum `ribbons' and intricate outflows
Qiu-yi Luo, Tie Liu, Aaron T. Lee +31
One of the most poorly understood aspects of low-mass star formation is how multiple-star systems are formed. Here we present the results of Atacama Large Millimeter/submillimeter…
Density Structure of Centrally Concentrated Prestellar Cores from Multi-scale Observations
Dipen Sahu, Sheng-Yuan Liu, Doug Johnstone +23
Starless cores represent the initial stage of evolution toward (proto)star formation, and a subset of them, known as prestellar cores, with high density (~ 10^6 cm^-3 or higher) an…

Dust polarized emission observations of NGC 6334; BISTRO reveals the details of the complex but organized magnetic field structure of the high-mass star-forming hub-filament network
D. Arzoumanian, R. Furuya, T. Hasegawa +145
[Abridged] Filaments and hubs have received special attention recently thanks to studies showing their role in star formation. While the column density and velocity structures of b…
On filament fragmentation and the impact of ambient environment on it
S. Anathpindika, J. Di Francesco
Filaments are crucial intermediaries in the star formation process. Recent observations of filaments show that - \textbf{(i)} a number of them are non-singular entities, and rather…

The JCMT BISTRO survey: alignment between outflows and magnetic fields in dense cores/clumps
Hsi-Wei Yen, Patrick M. Koch, Charles L. H. Hull +43
We compare the directions of molecular outflows of 62 low-mass Class 0 and I protostars in nearby (<450 pc) star-forming regions with the mean orientations of the magnetic fields o…
Ubiquitous supersonic component in L1688 coherent cores
Spandan Choudhury, Jaime E. Pineda, Paola Caselli +15
Context : Star formation takes place in cold dense cores in molecular clouds. Earlier observations have found that dense cores exhibit subsonic non-thermal velocity dispersions. In…
Protoplanetary disk masses in NGC 2024: Evidence for two populations
Sierk E. van Terwisga, Ewine F. van Dishoeck, Rita K. Mann +8
Protoplanetary disks in dense, massive star-forming regions are strongly affected by their environment. How this environmental impact changes over time is an important constraint o…
ALMA ACA and Nobeyama observations of two Orion cores in deuterated molecular lines

We mapped two molecular cloud cores in the Orion A cloud with the ALMA ACA 7-m Array and with the Nobeyama 45-m radio telescope. These cores have bright ND emission in sing…
The Formation of Stars -- From Filaments to Cores to Protostars and Protoplanetry Disks
James Di Francesco, Helen Kirk, Doug Johnstone +16
Star formation involves the flow of gas and dust within molecular clouds into protostars and young stellar objects (YSOs) due to gravity. Along the way, these flows are shaped sign…
