薄层近似中的能量守恒:VI。泡沫和超级泡沫

Energy conservation in the thin layer approximation: VI. Bubbles and super-bubbles

Lorenzo Zaninetti

摘要:

在薄层近似的框架下,我们对两种类型的星际介质(ISM)建立了能量守恒模型。特别是,我们分析了ISM中存在的自引力和高斯ISM产生的不对称性的推进壳。模拟的天体物理目标是费米泡、局域泡和W4超泡。图像的理论被应用到梨形曲线,它允许导出一些解析公式的情况下,光学薄介质中观察到的强度。

英文摘要:

We model the conservation of energy in the framework of the thin layer approximation for two types of interstellar medium (ISM). In particular, we analyse an ISM in the presence of self-gravity and a Gaussian ISM which produces an asymmetry in the advancing shell. The astrophysical targets to be simulated are the Fermi bubbles, the local bubble, and the W4 super-bubble. The theory of images is applied to a piriform curve, which allows deriving some analytical formulae for the observed intensity in the case of an optically thin medium.
