对31颗经典星系新星和4颗复发新星的距离，用不同的方法获得了绝对星等和消光数据。建立了一个新的绝对星等- t3时间关系。我们发现了两组新星：光曲线平滑、绝对星等在-8 ~ -11之间的快速新星和结构光曲线在-6 ~ -7之间的快速新星、缓慢新星和非常缓慢新星。I族在远高于爱丁顿极限的光度处表现出准瞬时质量损失。第二组显示出一颗膨胀的白矮星在爱丁顿极限处持续的辐射。描述了一种适用于新光度标定的新星光曲线分类方案，并对95颗新星进行了应用。
For 31 classical galactic novae and four recurrent novae distances, absolute magnitudes and extinction data are derived by different methods. A new absolute magnitude - t3 time relation is established. Two groups of novae are found: very fast and fast novae with smooth light curves and absolute magnitudes between -8 and -11, and fast, slow, and very slow novae with structured light curves and absolute magnitudes between -6 and -7. Group I exhibits quasi-instantaneous mass loss at a luminosity far above the Eddington limit. Group II exhibits continued radiation at the Eddington limit from a bloated white dwarf. A classification scheme for nova light curves which is useful in the context of the new luminosity calibration is described and applied to 95 novae.
