Type Ia Supernovae (SNe Ia) are widely used as standard candles to probe the Universe. However, how these fierce explosions are produced itself is still a highly debated issue. There are mainly two popular models for SNe Ia: the double-degenerate scenario and the single-degenerate scenario. The double-degenerate scenario suggests that SNe Ia are produced by the coalescence of two degenerate white dwarfs, while the single-degenerate scenario suggests that the continuous accretion of a single degenerate white dwarf from its normal stellar companion will finally lead to a disastrous explosion when it is over-massive, resulting in an SN Ia. The rapid development of the gravitational wave astronomy sheds new light on the nature of SNe Ia. In this study, we calculate the gravitational wave emissions of double white dwarf coalescences and compare them with the sensitivities of several upcoming detectors. It is found that the gravitational wave emissions from double white dwarf mergers ...

双白矮星合并的引力波发射

Ia型超新星（SNe Ia）被广泛用作探测宇宙的标准蜡烛。但是，这些激烈的爆炸本身如何产生仍然是一个备受争议的问题。用于SNe Ia的流行模型主要有两种：双退化场景和单退化场景。双重简并的情况表明，SNe Ia是由两个简并的白矮星的结合产生的，而单简并的情况表明，单个简并的白矮星从其正常恒星伴星的连续积聚最终会导致灾难性的爆炸。它的质量过大，从而导致SN Ia。引力波天文学的迅速发展为SNe Ia的性质提供了新的思路。在这个研究中，我们计算了双白矮星合并的引力波发射，并将它们与即将推出的几种探测器的灵敏度进行比较。发现双白矮星合并产生的引力波...
