超新星中微子的总能量与中子星的潮汐形变和Binding Energy

Total Energy in Supernova Neutrinos and the Tidal Deformability and Binding Energy of Neutron Stars

Brendan Reed, C. J. Horowitz

摘要:

超新星中微子辐射的能量是一个与中子星引力结合能密切相关的基本量。近年来,中子星的潮汐形变受到引力波观测的制约。通过对几个状态方程的研究,我们发现潮汐形变与中子星的结合能之间有很强的相关性。我们利用这种相关性来提高对中子星的结合能和超新星中中微子总能量的预测。我们找到了一个形成于$\sim1.5\times 10^{53}$尔格超新星中的中子星的最小结合能。如果超新星中的中微子能量明显低于这个值,这将强烈表明新的未观测到的粒子正在带走一些超新星能量。另一方面,如果中微子的能量高于$\sim 6\times 10^{53}$尔格,这将强烈暗示一个(也许令人惊讶的)大质量中子星的形成。

英文摘要:

The energy radiated in supernova neutrinos is a fundamental quantity that is closely related to the gravitational binding energy of a neutron star. Recently the tidal deformability of neutron stars was constrained by gravitational wave observations. By considering several equations of state, we find a strong correlation between the tidal deformability and neutron star binding energy. We use this correlation to sharpen predictions of the binding energy of neutron stars and the total neutrino energy in supernovae. We find a minimum binding energy for a neutron star formed in a supernova of $\sim1.5\times 10^{53}$ ergs. Should the neutrino energy in a supernova be significantly below this value, it would strongly suggest new unobserved particles are carrying away some of the supernova energy. Alternatively, if the neutrino energy is observed above $\sim 6\times 10^{53}$ ergs, it would strongly imply the formation of a (perhaps surprisingly) massive neutron star.
