论文摘要
我们报告了2012年1月11日发生的反复发生的Nova M31N 2017-01E的先前未知的喷发。早期的爆发是由Pan-Starts检测到的，并发生在2017年1月31日爆发之前的1847天（5.06 YR）（5.06 YR）（M31N 2017-01E）。现在已经看到，NOVA总共有四次记录的爆发（M31n 2012-01c，2017-01e，2019-09d和2022-03d），平均爆发仅在$ 929.5 $ 929.5 \ pm6.8 $ days（$ 2.545 \ pm0.019 $ yr）之间，第二个已知的reprencie sective time nove nove retister。我们还表明，有一个蓝色变量源（$ \ langle v \ rangle = 20.56 \ pm0.17 $，$ b-v \ simeq0.045 $），显然与Nova的位置相吻合，该位置表现出14.3 D周期性。提出了系统的可能模型，但没有一个完全令人满意。
We report the discovery of a previously unknown eruption of the recurrent nova M31N 2017-01e that took place on 11 January 2012. The earlier eruption was detected by Pan-STARRS and occurred 1847 days (5.06 yr) prior to the eruption on 31 January 2017 (M31N 2017-01e). The nova has now been seen to have had a total of four recorded eruptions (M31N 2012-01c, 2017-01e, 2019-09d, and 2022-03d) with a mean time between outbursts of just $929.5\pm6.8$ days ($2.545\pm0.019$ yr), the second shortest recurrence time known for any nova. We also show that there is a blue variable source ($\langle V \rangle = 20.56\pm0.17$, $B-V\simeq0.045$), apparently coincident with the position of the nova, that exhibits a 14.3 d periodicity. Possible models of the system are proposed, but none are entirely satisfactory.
