Project C5 studies the conditions and the impact of star formation in state-of-the-art, 3D MHD simulations with e.g. radiative transfer and a chemical network. In different galactic environments, we study the formation and collapse of self-consistently forming, turbulent and filamentary molecular clouds by means of novel galaxy zoom simulations. We investigate the impact of feedback of the forming massive stars, which triggers star formation, drives turbulence, and disperses the parental molecular clouds. In a further "deep-zoom” step we will disentangle the accretion of dense gas through the complex network of filaments onto cores and hubs where massive star formation proceeds.

C5项目研究星星形成的条件和影响，采用最先进的3D MHD模拟，例如辐射传输和化学网络。在不同的星系环境中，我们研究的形成和崩溃的自洽形成，湍流和对流分子云的新颖的星系变焦模拟。我们研究了形成中的大质量恒星的反馈的影响，它触发了星星的形成，驱动湍流，并分散了父母的分子云。在进一步的“深度放大”步骤中，我们将解开致密气体通过复杂的细丝网络到大质量星星形成过程中的核心和枢纽的吸积。
