摘要
分子云是研究恒星形成过程的主要场所。这些云含有丝状结构和核心,是年轻恒星形成的重要场所。恒星形成过程的研究采用了各种技术,包括追踪磁场的极坐标测量法。在这篇小型综述和简短报告中,我们汇集了(主要来自印度研究界的)为了解湍流和磁场在恒星形成过程中的作用所做的努力。这是 ISM 中与引力竞争的两个组成部分,而引力是气体塌缩形成恒星的主要原因。我们还尝试利用分子云的模拟来研究这种竞争。我们列出了对反馈和磁场的综合研究,以了解两种能量之间的相互作用在确定目前观测到的恒星形成效率方面的重要性。我们列出了现有的和即将出现的具有追踪磁场所需的偏振能力的设施。我们还指出了印度各界与国外设施之间正在进行的和希望进行的合作的重要性,以便更多地了解湍流和磁场在恒星形成过程中的作用。
Molecular clouds are prime locations to study the process of star formation. These clouds contain filamentary structures and cores, which are crucial sites for the formation of young stars. The star-formation process has been investigated using various techniques, including polarimetry, for tracing magnetic fields. In this small review-cum-short report, we put together the efforts (mainly from the Indian community) to understand the roles of turbulence and magnetic fields in star formation. These are two components of the ISM competing against gravity, which is primarily responsible for the collapse of gas to form stars. We also include attempts made using simulations of molecular clouds to study this competition. Studies on feedback and magnetic fields are combined and listed to understand the importance of the interaction between two energies in setting the current observed star formation efficiency. We have listed available and upcoming facilities with the polarization capabilities needed to trace magnetic fields. We have also stated the importance of ongoing and desired collaborations between Indian communities and facilities abroad to shed more light on the roles of turbulence and magnetic fields in the process of star formation.
