论文摘要
我们讨论了一种场景，在Novae爆炸期间产生TEV中微子。有人认为，由于重新连接了白色矮人的强磁场，哈德子在新星的内部被加速至非常高的能量。预计Hadron在加速过程中或在赤道风的往复期间已经有效地与风密集的物质相互作用。我们计算中微子光谱，并在几个Novae的情况下估计Icecube望远镜中的MUON中微子事件发生率。通常，当前中微子探测器不太可能检测到这些事件速率。但是，对于观察者的有利位置，不仅可以从最近在GEV $γ$ -rays中检测到的Novae级别检测到一些中微子事件。从Novae观察到的GEV $γ$ ray排放不能起源于此处讨论的模型，因为质子在白色矮人的几个出色的半径内加速了，即在与辐射场相互作用的GEV $γ$ rays中，预计GEV $γ$ -rays会严重吸收。
We discuss a scenario in which TeV neutrinos are produced during explosions of Novae. It is argued that hadrons are accelerated to very high energies in the inner part of a Nova wind, as a result of reconnection of the strong magnetic field of a White Dwarf. Hadrons are expected to interact efficiently with a dense matter of the wind, either already during the acceleration process or during their advection with the equatorial wind. We calculate the neutrino spectra, and estimate the muon neutrino event rates in the IceCube telescope, in the case of a few Novae. In general, those event rates are unlikely to be detected with the present neutrino detectors. However, for favourable location of the observer, some neutrino events might be detected not only from the class of Novae recently detected in the GeV $γ$-rays by the {\it Fermi}-LAT telescope but also from novae not detected in $γ$-rays. The GeV $γ$-ray emission observed from Novae cannot originate in terms of the model discussed here, since protons are accelerated within a few stellar radii of the White dwarf, i.e. in the region in which GeV $γ$-rays are expected to be severely absorbed in the interactions with the radiation field and the matter of the wind.
