论文摘要
中级和巨大的恒星驱动快速有力的各向同性风，与附近星团和周围星际介质（ISM）中的恒星的风相互作用。风向碰撞会在这些恒星周围产生天文波，其中包含热$ t \ sim 10^7 $ k气体，从绝热地扩展。随着个体气泡的扩展和碰撞，它们变得不稳定，可能会在星团中驱动湍流。在本文中，我们使用流体动力模拟对均匀云中密集的年轻恒星群进行建模，以研究与周围ISM的恒星风碰撞。我们对20个B型年轻序列星的质量分析集群建模，质量为3--17 $ M _ {\ odot} $。我们以$ \ sim $ 11的kyrs进化了风，并表明风主义碰撞和围绕B-Star的过度播放气泡混合了热气体，ISM材料在其演化的早期就产生了kolmogorov的湍流。我们讨论恒星风驱动的湍流如何影响群集中随后的恒星形成
Intermediate and massive stars drive fast and powerful isotropic winds that interact with the winds of nearby stars in star clusters and the surrounding interstellar medium (ISM). Wind-ISM collisions generate astrospheres around these stars that contain hot $T\sim 10^7$ K gas that adiabatically expands. As individual bubbles expand and collide they become unstable, potentially driving turbulence in star clusters. In this paper we use hydrodynamic simulations to model a densely populated young star cluster within a homogeneous cloud to study stellar wind collisions with the surrounding ISM. We model a mass-segregated cluster of 20 B-type young main sequence stars with masses ranging from 3--17 $M_{\odot}$. We evolve the winds for $\sim$11 kyrs and show that wind-ISM collisions and over-lapping wind-blown bubbles around B-stars mixes the hot gas and ISM material generating Kolmogorov-like turbulence on small scales early in its evolution. We discuss how turbulence driven by stellar winds may impact the subsequent generation of star formation in the cluster
