Oddly, the inferred elapsed time between ejection episodes, about 500 years, is too long to be explained by dynamic pulsations (in which the star contracts and expands, in a gentle tussle between gravity and gas pressure) and too short to represent therma

奇怪的是，不连续喷发的间隔据推估大约是500年，但这段时间实在太长而不能以动力搏动（恒星因重力与气体压力间温和的交互作用，而产生收缩与扩张的现象）来解释，不过却又短到无法用热力搏动（恒星被驱向非平衡状态）来描述。
