重新审视质量低于钱德拉塞卡的吸积白矮星。研究了使用扩展反应网络对预测能量产生和起爆层特性的影响。结果表明，所考虑的场景可以是 $\alpha p$ 进程与 p 进程以及我们称为 pn 进程的 rp 进程的变体相结合的站点。我们定义了喷射物中p核素丰度分布的条件，其中包括令人费解的轻Mo和Ru同位素，模仿太阳系的同位素。
He-accreting white dwarfs with sub-Chandrasekhar mass are revisited. The impact of the use of an extended reaction network on the predicted energy production and characteristics of the detonating layers is studied. It is shown that the considered scenario can be the site of an $\alpha p$-process combined with a p -process and with a variant of the rp -process we refer to as the pn -process. We define the conditions under which the derived distribution of the abundances of the p -nuclides in the ejecta, including the puzzling light Mo and Ru isotopes, mimics the solar-system one.
