Evolution of the Angular Momentum of Molecular Cloud Cores in Magnetized Molecular Filaments

The Astrophysical Journal
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 magnetized molecular filaments is still unclear.

Plasma Heating by Alfven Wave Filamentation: A Relevant Mechanism in the Solar Corona and the Interstellar Medium

The Astrophysical Journal, 1997
A mechanism for small-scale generation in magnetically dominated, homogeneous space plasmas is proposed, resulting from transverse collapse (filamentation) of weakly nonlinear, circularly polarized Alfven waves. It is argued that waves whose frequencies exceed a magnitude of about 10 Hz can significantly contribute to the heating of open coronal holes ...

Probing the Magnetic Fields and Dust Properties in the Young Embedded Star-forming Region AFGL 6366S Using Near-infrared and Optical Linear Polarimetry

The Astrophysical Journal
We present near-infrared (NIR) and optical linear polarimetry toward the partially embedded cluster AFGL 6366S. The polarization ranges from 0.44% to 10.3% in NIR and from 0.16% to 11.22% in the optical bands. The position angle spans 1°−179° in both the

Why Are (Almost) All the Protostellar Outflows Aligned in Serpens Main?

The Astrophysical Journal
We present deep 1.4–4.8 μ m JWST-NIRCam imaging of the Serpens Main star-forming region and identify 20 candidate protostellar outflows, most with bipolar structure and identified driving sources. The outflow position angles (PAs) are strongly correlated,

Investigations of MWISP Filaments. I. Filament Identification and Analysis Algorithms, and Source Catalog

The Astrophysical Journal Supplement Series
Filaments play a crucial role in providing the necessary environmental conditions for star formation, actively participating in the process. To facilitate the identification and analysis of filaments, we introduce Directional and Positional Consistency ...
