B-fields In STar-forming Region Observations (BISTRO): Dual-Wavelength Constraints on Size-Dependent Grain Alignment in Star-Forming Regions
Ray S. Furuya, David Berry, Pierre Bastien +65
We compared 450 and 850 m POL-2 observations from the James Clerk Maxwell Telescope at resolution. The median absolute difference in polarization angle between bands is…
B-fields In STar-forming Region Observations (BISTRO): Technical Foundations for Quantitative 450/850 m JCMT SCUBA-2/POL-2 Polarimetry
Ray S. Furuya, David Berry, Pierre Bastien +59
We present five technical validations of SCUBA-2/POL-2 polarimetry on the James Clerk Maxwell Telescope at 450 and 850 m, using 174 archival fields in 69 molecular cloud regions…
Dust Growth in Evolving Filamentary Molecular Clouds: Signatures in Ionization, Resistivity, and Infrared Scattering
Hayato Uchimura, Yoshiaki Misugi, Daisuke Takaishi +4
Studies of dust growth in molecular clouds often prescribe the collapse history, leaving unclear how magnetic regulation of core formation shapes dust evolution and its observable…
Corona Australis 151: an extremely young protostar
E. Redaelli, S. Spezzano, P. Caselli +9
Context. Prestellar cores are the birthplace of stars and planetary systems, but they are short-lived objects, since the initial stages of dense core evolution, collapse, and the f…
Formation of Isotopically Heterogeneous Molecular Cloud Cores in Filamentary Molecular Clouds
Yoshiaki Misugi, Shu-ichiro Inutsuka, Taishi Nakamoto +1
Meteorite analysis shows that the older solids of the solar system, such as the calcium-aluminum-rich inclusions (CAIs), have isotopic inhomogeneity. This indicates that the isotop…
Probing the ion-neutral drift velocity towards the L1544 prestellar core: Detection of ambipolar diffusion using ND and para-NHD
Doris Arzoumanian, Silvia Spezzano, Tommaso Grassi +9
The dynamical role of the magnetic field in the star formation process is tightly linked to the coupling between matter and the field. This coupling is due to the interaction betwe…
A differentiable and optimizable 3D model for interpretation of observed spectral data cubes
T. Grassi, J. E. Pineda, S. Spezzano +6
Molecular spectral cubes of prestellar cores encode the information on the physical and chemical properties of these objects along the line of sight. To retrieve this information,…
Ion-Neutral Drift Velocity as a Diagnostic of Dust Growth and Magnetic Field in Star-Forming Environments
Haruka Fukihara, Yusuke Tsukamoto, Hiroyuki Hirashita +2
Recent observations have revealed that the ion-neutral drift velocity in star-forming molecular clouds and dense cores is on the order of 100 m s^-1. Theoretical studies have shown…
Fragmenting Filaments and Evolving Cores -- Insights from Dust Polarisation Study of a filament in Northern Orion B
Kshitiz K. Mallick, Doris Arzoumanian, Satoko Takahashi +5
We present an analysis of polarised dust emission at 850 micron for a parsec long filament in the northern part of the Orion B molecular cloud. The region was observed by the JCMT…
A statistical approach for interpreting polarized dust emission of the filamentary molecular clouds toward the estimate of 3D magnetic field structure
Haruka Fukihara, Daisuke Takaishi, Yoshiaki Misugi +2
In this study, we perform 3D magnetohydrodynamics (MHD) simulations of filamentary molecular clouds. We then generate synthetic observations based on the simulation results. Using…
Evolution of the Angular Momentum of Molecular Cloud Cores in Magnetized Molecular Filaments
Yoshiaki Misugi, Shu-ichiro Inutsuka, Doris Arzoumanian +1
The angular momentum of molecular cloud cores plays a key role in the star formation process. However, the evolution of the angular momentum of molecular cloud cores formed in magn…
Evolution of the Angular Momentum of Molecular Cloud Cores Formed from Filament Fragmentation
Yoshiaki Misugi, Shu-ichiro Inutsuka, Doris Arzoumanian
The angular momentum of molecular cloud cores plays an essential role in the star formation process. However, the time evolution of the angular momentum of molecular cloud cores is…
Velocity structure of the 50 pc-long NGC 6334 filamentary cloud: Hints of multiple compressions and their impact on the cloud properties?
Doris Arzoumanian, Delphine Russeil, Annie Zavagno +8
[Abridged] The interstellar medium is observed to be organised in filamentary structures, as well as neutral (HI) and ionized (HII) bubbles. The expanding nature of these bubbles m…
An Origin for the Angular Momentum of Molecular Cloud Cores: a Prediction from Filament Fragmentation
Yoshiaki Misugi, Shu-ichiro Inutsuka, Doris Arzoumanian
The angular momentum of a molecular cloud core plays a key role in star formation, since it is directly related to the outflow and the jet emanating from the new-born star and it e…
