论文摘要
超大黑洞的近社区不仅包含浓缩气体和灰尘，还包含恒星大小的物体，例如星星，恒星质量的黑洞，中子星和尘埃笼罩的物体，完全构成了密集的核星群。这些对象与积聚培养基相互作用，它们会扰动积聚流的原本准平台配置。我们研究了恒星的通道如何通过GRMHD 2D和3D模拟影响黑洞气态环境。我们专注于积聚率的变化以及等离子体流出的斑点的相关出现。
The close neighbourhood of a supermassive black hole contains not only accreting gas and dust, but also stellar-sized objects like stars, stellar-mass black holes, neutron stars, and dust-enshrouded objects that altogether form a dense nuclear star-cluster. These objects interact with the accreting medium and they perturb the otherwise quasi-stationary configuration of the accretion flow. We investigate how the passages of a star can influence the black hole gaseous environment with GRMHD 2D and 3D simulations. We focus on the changes in the accretion rate and the associated emergence of outflowing blobs of plasma.
