https://kknews.cc/other/939agaj.html 这颗代号为M31N 2008-12a的仙女座恒星早在2008年经历新星爆炸期间就已经被发现 https://www.sciencedaily.com/releases/2019/01/190109142653.htm (https://www.sciencedaily.com/images/2019/01/190109142653_1_540x360.jpg) A composite image of Liverpool Telescope data (bottom left) and Hubble Space Telescope data (top right) of the nova super-remnant. M31N 2008-12a is in the centre. Astrophysicists have found the first ever evidence of gigantic remains being formed from repeated explosions on the surface of a dead star in the Andromeda Galaxy, 2.5 million light years from Earth. The remains or "super-remnant" measures almost 400 light years across. For comparison, it takes just 8 minutes for light from the Sun to reach us https://arxiver.wordpress.com/2016/11/07/m31n-2008-12a-the-remarkable-recurrent-nova-in-m31-ssa/ https://arxiv.org/abs/1607.08082 主題: 回覆： 超新星爆发前夕恒星 M31N 2008-12a 發現反複噴發噴出物 作者: peter 於 2019-01-10 08:00:52 http://d.hatena.ne.jp/meineko/touch/20150829
