Contribution

It summarizes current observational studies and ongoing projects investigating magnetic fields in star-forming filaments, highlighting recent progress and future directions.

Findings

Magnetic fields are crucial in filament evolution.

POLSTAR survey provides new data on magnetic field orientations.

Understanding magnetic influence aids star formation theories.

Abstract

Cold, dense filaments, some appearing as infrared dark clouds, are the nurseries of stars. Tremendous progress in terms of temperature, density distribution and gas kinematics has been made in understanding the nature of these filaments. However, very little is known about the role played by magnetic fields in the evolution of these filaments. Here, I summarize the recent observational efforts and ongoing projects (POLSTAR survey) in this direction.
