用中微子暴能谱估算银河系恒星坍缩距离
Estimations of the Distances of Stellar Collapses in the Galaxy by Analyzing the Energy Spectrum of Neutrino Bursts
摘要:
目前的中微子望远镜,根据其特殊的功能,可以重建银河系爆发的中微子光谱。由于光学对应物可能不可用,因此希望手头有替代方法来仅使用中微子数据估计超新星爆炸的距离。在这项工作中,我们提出的方法,我们提出的初步结果估计距离银河系超新星的中微子爆发的光谱形状和假设的基础上释放一个典型的超新星爆炸由于恒星坍缩的引力结合能。
英文摘要:
The neutrino telescopes of the present generation, depending on their specific features, can reconstruct the neutrino spectra from a galactic burst. Since the optical counterpart could be not available, it is desirable to have at hand alternative methods to estimate the distance of the supernova explosion using only the neutrino data. In this work we present preliminary results on the method we are proposing to estimate the distance from a galactic supernova based only on the spectral shape of the neutrino burst and assumptions on the gravitational binding energy released an a typical supernova explosion due to stellar collapses.
