Evolution of compressed clouds formed by filament coalescence. I. Oblique collisions
Raiga Kashiwagi, Kazunari Iwasaki, Kohji Tomisaka +1
Stars are thought to form predominantly within filamentary molecular clouds. Recent studies have suggested that active star formation, including the formation of stellar clusters a…
Hub Formation and Filament-Filament Collision: An Analytical Model
Kohji Tomisaka, Raiga Kashiwagi, Kazunari Iwasaki
Filaments are ubiquitous throughout the Galaxy. Massive star formation is often observed in hub-filament systems, where multiple filaments appear to be interconnected and merging.…
H Ortho-Para Spin Conversion on Inhomogeneous Grain Surfaces. II. impact of the rotational energy difference between adsorbed ortho-H and para-H and implication to deuterium fractionation chemistry
Kenji Furuya, Toshiki Sugimoto, Kazunari Iwasaki +2
We investigate how the H ortho-to-para ratio (OPR) and dueterium fractionation in star-forming regions are affected by nuclear spin conversion (NSC) on dust grains. Particular…
A Tale of Three: Magnetic Fields along the Orion Integral-Shaped Filament as Revealed by JCMT BISTRO survey
Jintai Wu, Keping Qiu, Frederick Poidevin +152
As part of the BISTRO survey, we present JCMT 850 m polarimetric observations towards the Orion Integral-Shaped Filament (ISF) that covers three portions known as OMC-1, OMC-2,…
The JCMT BISTRO Survey: The Magnetic Fields of the IC 348 Star-forming Region
Youngwoo Choi, Woojin Kwon, Kate Pattle +150
We present 850 m polarization observations of the IC 348 star-forming region in the Perseus molecular cloud as part of the B-fields In STar-forming Region Observation (BISTRO)…
