论文摘要
NOVA爆发对灾难变量（CVS）长期演变的影响是该领域中最不理解和深入讨论的主题之一。加以改进的杂技成分是建立一个具有已知特性的大量后诺维氏样本，从最容易访问的特性开始，即Orbitalperiod。在这里，我们报告了六个淡淡的Novae的新轨道周期：X CIR（3.71 h），Ilnor（1.62 h），Dy Pup（3.35 H），V363 SGR（3.03 H），V2572 SGR（3.75 H）和CQ Vel（2.7 H）。我们还修改了旧的Novae Oy Ara，RS汽车，V365CAR，V849 OPH，V728 SCO，WY SGE，XX TAU和RW UMI的时期。使用这些新数据并严格审查文献中旧诺瓦的轨道时期的可信度，我们建立了更新的时期分布。我们采用二元 - 静音代码来计算理论周期分布，并同时使用经验和经典处方，以进行相应的角动量损失。与观察数据相比，我们发现两个模型在3-4 h范围内都无法再现峰值，这表明尚不完全了解CVS abovethe abovethe abovethe abovethe abovethe abovethe gap的角动量损失。
The impact of nova eruptions on the long-term evolution of Cataclysmic Variables(CVs) is one of the least understood and intensively discussed topics in the field. Acrucial ingredient to improve with this would be to establish a large sample of post-novae with known properties, starting with the most easily accessible one, the orbitalperiod. Here we report new orbital periods for six faint novae: X Cir (3.71 h), ILNor (1.62 h), DY Pup (3.35 h), V363 Sgr (3.03 h), V2572 Sgr (3.75 h) and CQ Vel(2.7 h). We furthermore revise the periods for the old novae OY Ara, RS Car, V365Car, V849 Oph, V728 Sco, WY Sge, XX Tau and RW UMi. Using these new dataand critically reviewing the trustworthiness of reported orbital periods of old novae inthe literature, we establish an updated period distribution. We employ a binary-starevolution code to calculate a theoretical period distribution using both an empiricaland the classical prescription for consequential angular momentum loss. In comparisonwith the observational data we find that both models especially fail to reproduce thepeak in the 3 - 4 h range, suggesting that the angular momentum loss for CVs abovethe period gap is not totally understood.
