Abstract

A 2D dynamic model is utilized to investigate star formation in rotating filamentary molecular clouds (FMCs) amidst magnetic fields. The study reveals that the emergence of field stars is possible under both weak and strong magnetic fields due to the presence of low-density structures. The presence of a strong rotation in a strongly magnetized FMC Plays a crucial role in forming a combination of two binary pairs and two field stars. An intermediate-density structure in the presence of a moderate magnetic field can form a combination of binary stars and field stars, whereas, in very high dense filamentary molecular clouds, a low magnetic field may help to form binary stars or stellar associations. In a rapidly rotating and weakly magnetized highly dense cloud binary stars are formed, whereas, strong rotation and moderate magnetic field help to form stellar associations
