Low-energy neutrinos are clean messengers from supernovae explosions and probably carry unique insights into the process of stellar evolution. We estimate the expected number of events considering coherent elastic scattering of neutrinos off silicon nuclei, as would happen in Charge Coupled Devices (CCD) detectors. The number of expected events, integrated over a window of about 18 s, is $\sim$ 4 if we assume 10 kg of silicon and a supernovae 1 kpc away. For a a distance similar to the red supergiant Betelgeuse, the number of expected events increases to $\sim$ 30 - 120, depending on the supernovae model. We argue that silicon detectors can be effective for supernovae neutrinos, and might possibly distinguish between models for certain target masses and distances.

通过硅核相干散射探测超新星中微子

低能中微子是来自超新星爆炸的清洁信使，可能对恒星演化过程具有独特的见解。考虑到中微子在硅核上的相干弹性散射，我们估计了预期的事件数量，就像在电荷耦合器件 (CCD) 探测器中会发生的那样。如果我们假设有 10 kg 硅和 1 kpc 之外的超新星，则在大约 18 s 的窗口内积分的预期事件数量为 $\sim$ 4。对于类似于红超巨星参宿四的距离，预期事件的数量增加到 $\sim$ 30 - 120，具体取决于超新星模型。我们认为硅探测器可以有效检测超新星中微子，并且可能区分某些目标质量和距离的模型。
