标题： Pulsar Braking Index and Mass Accretion

摘要： 我证明了制动指数$N$，一个基本的脉冲星实验量，自然地与3的典型值不同，这些差异涉及质量吸积。 利用PSR1509-58和PSR0531+21的$N$测量值，我确定对于密度恒定的中子星，它们当前的质量吸积率分别为$(3.10\pm.51)\times10^{-5}$M年$^{-1}$和$(9.946\pm.089)\times10^{-5}$M年$^{-1}$，其中M是每个脉冲星的质量。 最后，我证明了质量吸积解决了维拉脉冲星大跳变起源这一突出的问题。 显示英文摘要

摘要： I show that the braking index, $N$, a fundamental pulsar experimental quantity, naturally differs from the canonical value of 3 by terms which involve mass accretion. Using the measured values of $N$ for PSR1509-58 and PSR0531+21, I determine that for constant density neutron stars their present mass accretion rates are $(3.10\pm.51)\times10^{-5}$ M year$^{-1}$ and $(9.946\pm.089)\times10^{-5}$ M year$^{-1}$ respectively, where M is the mass of each pulsar. Finally, I demonstrate that mass accretion removes the outstanding problem of the origin of the big glitches of the Vela Pulsar.
