标题： Comment on "Pulsar kicks via spin-1 color superconductivity"

摘要： 在近期的一篇论文中，Phys. Rev. Lett. 94, 211101 (2005) [hep-ph/0502166]，Schmitt 等人提出了一种新的机制来解释脉冲星的观测速度。该提出的解释基于超新星爆发数千年后温度低于 0.1 MeV 的冷却中子星各向异性发射中微子的现象。然而，虽然在超新星爆炸的第一分钟内中微子被大量产生，在之后的时间里中微子发射可以忽略不计。因此，所提出的机制不可行。 显示英文摘要

摘要： In a recent paper, Phys. Rev. Lett. 94, 211101 (2005) [hep-ph/0502166], Schmitt et al. have proposed a new mechanism to explain the observed velocities of pulsars. The proposed explanation is based on anisotropic emission of neutrinos from a cooling neutron star at temperatures below 0.1 MeV, thousands of years after the supernova. However, while neutrinos are copiously produced during the first minute of the supernova explosion, at later times the neutrino emission is negligible. Therefore, the proposed mechanism is not viable.
