Star formation is a complex multi-scale phenomenon that is of significant importance for astrophysics in general. Stars and star formation are key pillars in observational astronomy from local star forming regions in the Milky Way up to high-redshift galaxies. From a theoretical perspective, star formation and feedback processes (radiation, winds, and supernovae) play a pivotal role in advancing our understanding of the physical processes at work, both individually and of their interactions. In this review we will give an overview of the main processes that are important for the understanding of star formation. We start with an observationally motivated view on star formation from a global perspective and outline the general paradigm of the life-cycle of molecular clouds, in which star formation is the key process to close the cycle. After that we focus on the thermal and chemical aspects in star forming regions, discuss turbulence and magnetic fields as well as gravitational forces. Finally, we review the most important stellar feedback mechanisms.

GASP. XII. The variety of physical processes occurring in a single galaxy group in formation
GAS-Stripping Phenomenon in galaxies with MUSE（GASP）是一个旨在研究不同环境中邻近星系气体去除过程的计划。我们提出了四个星系的研究，是同一组（z= 0.06359）的一部分，并强调了众多的机制影响的空间分辨性能的组成员。一个星系是被动的，并显示出规则的恒星运动学。对它的恒星形成历史的分析表明，淬灭过程持续了几个Gyr，而恒星形成在整个盘中以类似的方式下降，与扼杀一致。另一个星系的特征是一个双组分恒星盘，其中有一个扩展的气体盘，形成于10^8年前，很可能是气体吸积的结果。第三个成员是一个位于星系群边缘的螺旋星系，但嵌入在一个暗条中。我们假设稀疏的星系际介质对稠密的环星系气体施加的压缩，在星系周围的一些云中打开了恒星形成的开关（“宇宙网增强”）。或者，冲压压力汽提也可能有效。最后，第四个星系是一个螺旋形的截断电离气体盘和未受干扰的恒星运动学。星系恢复压力的分析模型，以及它在星系团中的位置和速度，表明冲压压力是最有可能的物理机制。这是第一个群体剥脱的光学证据。
