论文摘要
我通过在两个或多个独立的光曲线中寻找重要，连贯和稳定的光学光度调制，以在两个或多个独立的光曲线中寻找大量的NOVA系统的轨道周期（P）大规模搜索。我发现了31个新的轨道时期。此外，根据它们的光谱能量分布，我还测量了与进化同伴的18个Novae的新时期，精度为30％。另外，我已经确认，改进并拒绝了46名Novae的P的先验主张。 （作为这项工作的一部分，我认识到5 Novae显示1--3个连贯，意义和短暂的周期性0.12--4.1天，因为这些周期是神秘的，因为它们不是轨道，旋转或超级峰时期。）我总共汇总了Novae的156个可靠P值的全面列表。 NOVA期间的直方图显示在0.059小时（85分钟）时的最低P，并且距离为0.071---0.111天（1.70--2.66小时）的周期间隙。 Novae（0.111天），类似Nova的系统（0.131天）和矮novae（0.141天）之间的周期间隙的上边缘显着差异。直方图的另一个问题是，31％的Nova系统已经发展出了伴侣，因此对其当前状态或进化没有模型或理解。对于有红色巨人同伴的诺维，尽管有主序和次级伴侣的隆起分数接近0.11--0.32，但隆起的人口中有15分。
I report on a large-scale search for the orbital periods (P) of most known nova systems, by looking for significant, coherent, and stable optical photometric modulation in two or more independent light curves taken mostly from the large surveys of TESS, Kepler, AAVSO, SMARTS, OGLE, ASAS, and ZTF. I have discovered 31 new orbital periods. Further, I have measured new periods for 18 novae with evolved companions, to 30 per cent accuracy, as based on their spectral energy distribution. Also, I have confirmed, improved, and rejected prior claims for P in 46 novae. (As part of this effort, I recognize that 5 novae display 1--3 coherent, significant, and transient periodicities 0.12--4.1 days, with these being mysterious as not being the orbital, spin, or superhump periods.) In all, I have compiled a comprehensive list of 156 reliable P values for novae. The histogram of nova periods shows a minimum P at 0.059 hours (85 minutes), and a Period Gap from 0.071--0.111 days (1.70--2.66 hours). The upper edge of the Period Gap is significantly different between novae (0.111 days), nova-like systems (0.131 days), and dwarf novae (0.141 days). A further issue from the histogram is that 31 per cent of nova systems have evolved companions, for which there has been no models or understanding for their current state or evolution. For the novae with red giant companions, 15-out-of-20 are in the bulge population, despite novae with main-sequence and subgiant companions having bulge fractions near 0.11--0.32.
