论文摘要
非常巨大的恒星偶尔会在巨大喷发中驱逐材料，这是由连续辐射压力而不是爆炸波驱动的。其中一些在总辐射输出中竞争超新星的竞争，质量损失对于随后的进化至关重要。有些是超新星冒名顶替者，包括SN前体爆发，而另一些则是真正的SN事件，这些事件被先前弹出的材料所笼罩。传统上，发出的发光传统上引用了发光的蓝色变量恒星（LBV），尽管这种连接尚未确定。经过四十年的研究，巨型喷发和LBV事件的基本原因仍然难以捉摸。这篇综述概述了基本的相关物理，并简要摘要了基本的观察事实。描述了不透明流出的光谱和新兴辐射温度的原因。许多提出的机制在恒星的光球，其铁不透明度区域以及其中部地区的不稳定性中被注意到。这里的一些言论和猜想尚未在已发表的文献中熟悉。
Very massive stars occasionally expel material in colossal eruptions, driven by continuum radiation pressure rather than blast waves. Some of them rival supernovae in total radiative output, and the mass loss is crucial for subsequent evolution. Some are supernova impostors, including SN precursor outbursts, while others are true SN events shrouded by material that was ejected earlier. Luminous Blue Variable stars (LBV's) are traditionally cited in relation with giant eruptions, though this connection is not well established. After four decades of research, the fundamental causes of giant eruptions and LBV events remain elusive. This review outlines the basic relevant physics, with a brief summary of essential observational facts. Reasons are described for the spectrum and emergent radiation temperature of an opaque outflow. Many proposed mechanisms are noted for instabilities in the star's photosphere, in its iron opacity peak zones, and in its central region. Some of the remarks and conjectures here have not yet become familiar in the published literature.
