论文摘要
众所周知，Nova爆发的发展是由白矮人（WD）质量及其从捐助者中积聚质量的速率确定的。该领域的进步之一是理解，即新星喷发的发生取决于信封中重元素的存在，并且这些元素的浓度高度取决于分配的积聚时间。这导致了许多特征的喷发与弹出材料中重元素的质量分数相关，但是，始终认为积聚的材料具有太阳金属性。在这里，我们探索了两种高度富集材料的材料的1.25 $ m_ \ odot $ wd上的整个积聚率范围，并发现富集对高积聚率的某些特征产生影响，而富集对低积聚率的影响则可以忽略不计。我们进一步发现，众所周知，热核失控的点火取决于临界质量的积累，实际上取决于临界量的重量较重元素的积累。
The development of a nova eruption is well known to be determined by the white dwarf (WD) mass and the rate at which it accretes mass from its donor. One of the advancements in this field is the understanding that the occurrence of a nova eruption depends on the presence of heavy elements in the envelope, and that the concentration of these elements is highly dependent on the time allotted for accretion. This results in many features of the eruption being correlated with the mass fractions of heavy elements in the ejected material, however, the accreted material is always assumed to be of solar metallicity. Here we explored the entire range of accretion rates onto a 1.25$M_\odot$ WD for two cases of highly enriched accreted material and find enrichment to have an influence on certain features for high accretion rates, while the effect of enrichment on low accretion rates is negligible. We further find that the ignition of the thermonuclear runaway which is known to be dependent on the accumulation of a critical mass, is actually dependent on the accumulation of a critical amount of heavy elements.
