论文摘要
我得出了所有402个已知银河新星的总体最佳距离，并收集了许多属性。核心是74个Novae，具有新的Gaia数据发布中的准确视差。对于所需的先验，我基于旧方法（包括膨胀可视性和灭绝距离）收集了171个距离。此外，我在峰值和灭绝措施处收集了V量，以便在峰值下产生绝对幅度，然后作为先验的粗距离得出一个粗距离。此外，我已经认识到，已知的Novae的41％集中在凸起中，其中68％距离银河中心<5.4度，因此165个凸起的Novae必须具有8000+-750 parsecs的距离。将所有这些放在一起，我派出了所有402名Novae的距离，其中220个距离的准确性高于30％。我发现圆盘的指数尺度高度为140+-10 pc。平均峰值绝对V型为-7.45，RMS散射为1.33 mag。这些峰值发光度与M_V，峰= -7.6 + 1.5 * log [T_3 / 30]的下降速率显着相关（T_3）。关于这种关系的巨大分散掩盖了许多较小的数据集中的相关性，并且使这种关系对物理模型无用。凸起的novae与所有财产中的碟片都没有区别，只是具有红色巨型伴侣星星的诺维尔（Novae）强烈偏爱居住在凸起的人群中。
I derive the overall best distances for all 402 known galactic novae, and I collect their many properties. The centrepiece is the 74 novae with accurate parallaxes from the new Gaia data release. For the needed priors, I have collected 171 distances based on old methods (including expansion parallaxes and extinction distances). Further, I have collected the V-magnitudes at peak and the extinction measures, so as to produce absolute magnitudes at peak and then derive a crude distance as a prior. Further, I have recognized that 41 per cent of the known novae are concentrated in the bulge, with 68 per cent of these <5.4 degrees from the galactic centre, so the 165 bulge novae must have distances of 8000+-750 parsecs. Putting this all together, I have derived distances to all 402 novae, of which 220 have distances to an accuracy of better than 30 per cent. I find that the disc novae have an exponential scale height of 140+-10 pc. The average peak absolute V-magnitude is -7.45, with an RMS scatter of 1.33 mag. These peak luminosities are significantly correlated with the decline rate (t_3 in days) as M_V,peak = -7.6 + 1.5 * Log[t_3 / 30]. The huge scatter about this relation masks the correlation in many smaller datasets, and makes this relation useless for physical models. The bulge novae are indistinguishable from the disc novae in all properties, except that the novae with red giant companion stars have a strong preference for residing in the bulge population.
