Hub-filament systems and the growth of massive stars: episodic accretion, clustered environments, and projection effects
Dana Makarova, Dana Alina, Paolo Padoan +4
The processes controlling the early mass growth of future massive stars remain poorly understood, particularly the connection of this growth to star clustering and hub-filament sys…
Interstellar filament detection and characterization: methods and implications for studies of magnetized interstellar medium
Dana Alina
Filamentary structures are ubiquitous in the interstellar medium and play a key role in the evolution of molecular clouds and star formation. Their morphology and relative orientat…
Statistical analysis of the relative orientations between filaments and magnetic fields using Herschel and Planck data in star-forming regions
Jonathan Oers, Isabelle Ristorcelli, Katia Ferrière +4
Observations and simulations of the interstellar medium both suggest that magnetic fields play a key role in the formation and evolution of filaments and in the process of star for…
B-Fields and Star Formation across Scales with TRAO (B-FROST): CO Abundances, Dynamics and Relative Orientations in the Translucent High Latitude Cloud MBM12
J. M. Vorster, J. Montillaud, M. Juvela +14
In our Galaxy, the average star formation efficiency is of the order of a few percent. We investigated the high-latitude molecular cloud MBM12 as part of the B-fields and star form…
Discovery of a Compact Hub-Filament System in G286.21+0.17 with JWST and ALMA: Insights into Protocluster Formation and Competitive Accretion
L. K. Dewangan, N. K. Bhadari, Ram K. Yadav +17
We present a multi-wavelength study of the massive protocluster G286.21+0.17 (G286) using \emph{JWST} near-infrared imaging and ALMA HCO(1--0) observations. The \emph{…
MAJORS II: HCO+& HCN Abundances in W40
René Plume, David J. Eden, Malcolm J. Currie +34
We present observations of HCN and HCO J = in the central region of the W40 massive star forming region. The observations were taken as part of a p…
