Marcin would work in the area of computational star formation/massive star feedback. Molecular clouds are large reservoirs of gas and dust, which collapse under gravity to form dense star-forming cores. As stars form, jets and winds are produced and interact with the molecular cloud surrounding them. Shocks are then driven into the clouds sweeping up material. Massive stars are thought to be particularly effective at destroying these environments, and thus at limiting the rate of star formation in galaxies. In this project state-of-the-art computational fluid dynamics codes will be used to simulate the interaction of dusty flows and/or radiation fields with their surrounding environment. This study will yield significant new insights into the nature of the interaction; for instance, how it depends on the presence of dust and/or on the porosity of the surroundings.

马辛将在计算恒星形成/大质量恒星反馈领域工作。分子云是气体和尘埃的大型储存库，在重力作用下坍塌形成致密的恒星形成核心。当恒星形成时，喷流和风就会产生，并与它们周围的分子云相互作用。然后，冲击波被推入云层，卷起物质。大质量恒星被认为在摧毁这些环境方面特别有效，因此在限制星系中恒星形成的速度方面也特别有效。在这个项目中，将使用最先进的计算流体力学程序来模拟尘埃流动和/或辐射场与其周围环境的相互作用。这项研究将对相互作用的性质产生重大的新见解；例如，它如何依赖于灰尘的存在和/或环境的孔隙度。
