论文摘要
有迹象表明,迫在眉睫的复发性nova t crb的第三次已知喷发是迫在眉睫的,并且在喷发前的多波长观测对于在系统爆发之前表征特征很重要。众所周知,T CRB以8 $ \,μ$ m的形式显示SIO基本振动功能。当发生预期的喷发时,当弹出材料涌入系统中红色巨人的风时,可能会使用Sio Maser发射来追溯到系统中产生的冲击。我们已经使用1亿埃菲尔斯伯格射电望远镜在$ \ upsilon = 1 $,$ \ upsilon = 2 $,$ j = 1 \ rightArrow0 $ transions中搜索$^{28} $ sio发射,分别为43.122 ghz和42.820〜GHz,而系统则分别为43.122 ghz和42.820〜GHz。我们没有发现这种排放的证据。
There are indications that the third known eruption of the recurrent nova T CrB is imminent, and multi-wavelength observations prior to the eruption are important to characterise the system before it erupts. T CrB is known to display the SiO fundamental vibrational feature at 8$\,μ$m. When the anticipated eruption occurs, it is possible that the shock produced when the ejected material runs into the wind of the red giant in the system may be traced using SiO maser emission. We have used the 100m Effelsberg Radio Telescope to search for $^{28}$SiO emission in the $\upsilon=1$, $\upsilon=2$, $J=1\rightarrow0$ transitions, at 43.122 GHz and 42.820~GHz respectively, while the system is in quiescence. We find no evidence for such emission.
