摘要

在层状星际盘中的超新星爆炸(SNe)可以产生垂直于盘的大规模结构和流出物。它们的形态和发射特征取决于爆炸的SNe数量、ISM垂直尺度高度、SNe所在的ISM盘上方高度和环境气体的平面中密度之间的相互关系。当观测到这样的面外气体结构时，确实可以描绘出驱动SNe的特性，并揭示出潜在星团的存在。尽管这种结构的形态和发射特性对周围气体的特征很敏感，但它们可以用来粗略估计星团的质量。

Bubbles and OB associations

Abstract Supernovae explosions (SNe) in a stratified interstellar disc can create large scale structures and outflows perpendicular to the disc. Their morphology and emission characteristics depend on interrelations between the number of exploded SNe, the ISM vertical scale height, the height above the ISM disc at which SNe are located, and the mid-plane density of ambient gas. When observed such out-of-plane gas structures do characterize properties of the driving SNe and reveal the presence of underlying stellar clusters. Even though the morphology and emission properties of such structures are sensitive to characteristics of ambient gas they might be used for rough estimates of the clusters’ mass.
