Rapidly Recurring Novae

最近几年，发现了一类新的热核新星，即重复出现10年的系统。这些现象是由来自施主的高质量和不断增长的白矮星提供动力的，并已成为领先的单简并Ia型超新星前身。该项目将继续对仙女座星系内的快速循环新星原型进行的开创性工作。最初，该项目将使用新获得的8m级望远镜的深时间光谱和晚期光谱来研究喷出物的演化和几何形状。该项目还将开发我们现有的流体力学模型代码，以探索由过去数千次喷发建立在原型周围的超级残留物。这种模拟将被用作预测工具，用于寻找其他经常性新星周围类似的超级残留物，特别是银河系的例子。最后，该项目将利用任何新爆发的候选系统，利用利物浦望远镜、LCO和尼尔·盖雷斯雨燕天文台等设施进行后续观测。

In recent years, a new class of thermonuclear novae has been uncovered; systems that recur on timescales < 10 years. These phenomena are powered by high mass and growing white dwarfs accreting at a high rate from a donor, and have become the leading single-degenerate supernova type Ia progenitor candidate. This project will continue the ground-breaking working being undertaken on the prototype rapid recurrent nova which resides within the Andromeda Galaxy. Initially the project will investigate the evolution and geometry of the ejecta using newly obtained deep and late-time spectra from 8+m-class telescopes. The project will also develop our existing hydrodynamic modelling code to explore the super remnant being built up around the prototype by many 1000s of past eruptions. This simulations will be used as predictive tools in the search for similar super remnants around other recurrent novae, particularly the Galactic examples. Finally, the project will exploit any newly erupting candidate systems, carrying out follow-up observations using facilities such as the Liverpool Telescope, LCO, and the Neil Gehrels Swift Observatory.
