ISM的NEI模型-湍流耗散和Hausdorff维数

NEI Modelling of the ISM - Turbulent Dissipation & Hausdorff Dimension

Miguel A. de Avillez, Dieter Breitschwerdt

摘要:

对湍流磁化ISM进行了高分辨率非理想磁流体动力学模拟,包括自引力和非平衡电离(NEI),考虑了H,He,C,N,O,Ne,Mg,Si,S和Fe的电离结构随时间的演化.这些运行覆盖了广泛的范围(从千秒差距到亚秒差距)的尺度,提供分辨率独立的信息,注入规模,扩展自相似性和最耗散结构的分形维数。

英文摘要:

High-resolution non-ideal magnetohydrodynamical simulations of the turbulent magnetized ISM, powered by supernovae types Ia and II at Galactic rate, including self-gravity and non-equilibriuim ionization (NEI), taking into account the time evolution of the ionization structure of H, He, C, N, O, Ne, Mg, Si, S and Fe, were carried out. These runs cover a wide range (from kpc to sub-parsec) of scales, providing resolution independent information on the injection scale, extended self-similarity and the fractal dmension of the most dissipative structures.
