论文摘要
我们提出了发现后9天开始的经典Nova爆炸的延时光谱。这些数据揭示了Fe II和[O I]中瞬态特征的外观。我们探索了此功能的不同模型，并得出结论，在经典NOVA事件之后，电圆盘冲击加热可以最好地解释它。环形圆盘可能在NOVAE中发挥重要作用，以说明被称为THEA的吸收系统，角动量的转移以及NOVA事件本身的可能触发。
We present time-lapse spectroscopy of a classical nova explosion commencing 9 days after discovery. These data reveal the appearance of a transient feature in Fe II and [O I]. We explore different models for this feature and conclude that it is best explained by a circumbinary disc shock-heated following the classical nova event. Circumbinary discs may play an important role in novae in accounting for the absorption systems known as THEA, the transfer of angular momentum, and the possible triggering of the nova event itself.
