摘要
我们报告了我们对第二个γ-ray脉冲星目录中列出的39毫秒脉冲星的费米大面积望远镜数据的分析。得到了脉冲星的光谱。我们用指数截断的幂函数对光谱进行了拟合，并找到了最适合的光子指数参数
和切断能量
Gev.这种光谱形状，包括MSP光谱的内在差异，可以用来寻找候选MSP和费米在高纬度探测到的不明类型的源。在其中一个−，PSRJ0614 MSP3329中，我们发现了高达60GeV的显著脉冲发射。因此，这一结果将这一MSP添加到已探测到的脉冲星群中，这些脉冲星的能量为数十GeV。将PSRJ0614γ-射线能谱与Crab和Vela脉冲星的−能谱进行了比较，讨论了超高能成分的可能发射机制。
ABSTRACT
We report our analysis of the Fermi Large Area Telescope data for 39 millisecond pulsars (MSPs) listed in the second γ-ray pulsar catalog. Spectra of the pulsars are obtained. We fit the spectra with a function of a power law with exponential cutoff, and find the best-fit parameters of photon index
and cutoff energy
GeV. This spectral shape, which includes the intrinsic differences in the spectra of the MSPs, can be used for finding candidate MSPs and unidentified types of sources detected by Fermi at high Galactic latitudes. In one of the MSPs, PSR J0614−3329, we find significant pulsed emission up to 60 GeV. The result has thus added this MSP to the group of pulsars that have been detected with pulsed emission at energies of tens of GeV. Comparing the γ-ray spectrum of PSR J0614−3329 with those of the Crab and Vela pulsars, we discuss possible emission mechanisms for the very high-energy component.
