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. This study provides an analytical framework for the DWP that helps predict the number and spatial distribution of stars under varying rotational and magnetic conditions within FMCs.
期刊介绍:
Astrophysics and Space Science publishes original contributions and invited reviews covering the entire range of astronomy, astrophysics, astrophysical cosmology, planetary and space science and the astrophysical aspects of astrobiology. This includes both observational and theoretical research, the techniques of astronomical instrumentation and data analysis and astronomical space instrumentation. We particularly welcome papers in the general fields of high-energy astrophysics, astrophysical and astrochemical studies of the interstellar medium including star formation, planetary astrophysics, the formation and evolution of galaxies and the evolution of large scale structure in the Universe. Papers in mathematical physics or in general relativity which do not establish clear astrophysical applications will no longer be considered.
The journal also publishes topically selected special issues in research fields of particular scientific interest. These consist of both invited reviews and original research papers. Conference proceedings will not be considered. All papers published in the journal are subject to thorough and strict peer-reviewing.
Astrophysics and Space Science features short publication times after acceptance and colour printing free of charge.
