解析表达式获得的绝对大小的新星在最大光，M B，和时间需要新星下降三个幅度从最大值，T 3。的关系表示的基本系统参数。利用M B和t3的表达式，得到了解析的M B -t3关系.这个关系式被用于确定河外星系的距离尺度。讨论了附加物理参数（如磁场）对所得关系的影响
Analytic expressions are obtained for the absolute magnitude of novae at maximum light, M B , and for the time it takes novae to decline three magnitudes from maximum, t 3 . The relations are expressed in terms of fundamental system parameters. Using the expressions for M B and t 3 , an analytic M B -t 3 relation is obtained. This relation is used in extragalactic distance scale determinations. The effects of additional physical parameters (such as the magnetic field) on the obtained relations are discussed
