  • 氨分子(NH3)是宇宙中探测到的第一种多原子星际分子,其谱线包含了很多频率接近的精细跃迁,便于计算分子云的温度、密度等物理参数。
    较之于一氧化碳分子(CO),氨分子示踪的气体密度高一个量级(n~10⁴ cm⁻³),在低温时不易冻结耗散,特别适于观测研究分子云中的冷致密气体成分。
    新疆天文台恒星形成与演化团组科研人员使用南山26米射电望远镜对天鹰座巨分子云的小质量恒星形成区(Serpens South)和大质量恒星形成区(W40)进行NH₃(1,1)和(2,2)谱线成图观测研究, ...

  • 他注意到该候选体的位置非常接近再发新星M31N 1984-07a(=M31N 2004-11f)(=M31N 2012-09a),因此可能是它的又一次爆发。
    他们也注意到M31N 2012-09a与M31N 1984-07a和M31N 2004-11f的位置非常接近,在误差允许的范围之内,因此将其列为再发新星候选体。

  • 这颗新星现在被编号为M31N 1923-12c,意为1923年12月在M31中发现的第3颗新星。
    它现在被编号为M31N 2012-01b,然而更有趣的是,天文学家发现它与M31N 1923-12c来自相同的前身天体,也就是说,这是一个少见的再发新星!
    图1:M31N 1923-12c(左)与M31N 2012-01b(右)(图像来源A. W. Shafter等人) 不知不觉我们来到了2021年7月3日。
    经查验,发现该候选体位置非常接近M31N 1923-12c和M31N 2012-01b,疑为M31N 1923-12c有记录的第三次爆发。
    该光谱证认AT 2021rno是一次新星爆发,并暗示M31N 1923-12c的再发周期短至9年。
  • 该目标发现时星等约15.8G,内部编号PSP20A,候选体编号PNV J00422347+4108228、AT 2020lye。
