论文摘要
最近发现了Fermi-Lat（$> $> $ 100 MEV）的Recurrent Nova RS Ophiuchi的高能排放，H.E.S.S。和魔术（$> $ 100 GEV），暗示了该辐射组件的可能起源。从观察到的高能量光子通量中，我们得出了不同能量范围中当前和未来中微子望远镜可以检测到的中微子事件的预期数量。我们发现，对于这种$ \ gamma $排放，辐射过程仍然是有效的解释。初步估计表明，使用“下一代”仪器IceCube-gen2，来自银河新Novae的中微子检测的预期数量为每十年$ \ sim $。鉴于当前的不确定性在NOVA爆发发生频率中，检测率可能会增加到每三年$ \ sim $ \ sim。
The recently discovered high energy emission from the recurrent nova RS Ophiuchi by Fermi-LAT ($>$ 100 MeV), H.E.S.S. and MAGIC ($>$ 100 GeV), hints towards a possible hadronic origin of this radiation component. From the observed high energy photon flux we derive the expected number of neutrino events that could be detected by present and future neutrino telescopes in the different energy ranges. We find that both hadronic and leptonic processes remain valid interpretations for this $ \ gamma $ emission. Preliminary estimates indicate that with the "next-generation" instrument IceCube-Gen2, the expected number of neutrino detections from Galactic novae is of the order of $\sim $ once per decade. Given the current uncertainties in the frequency of the occurrence of nova outbursts, the detection rate may possibly increase to up to once every $\sim $ three years.
