研究发现PSR J0630+19无法为HAWC J0630+186的高能辐射供电,因该脉冲星能量损失过低。

摘要:

3HWC J0630+186 是第三个高海拔水切伦科夫(HAWC)目录中非常高的能量伽马射线源之一,其起源和来源却尚未明确。唯一的可能相关源是 PSR J0630+19,该源距离 3HWC J0630+186 的中心有一定距离。目前,几 TeV 的脉冲星晕被认为是主导 TeV-PeV 伽马射线源,而 PSR J0630+19 首次由 Arecibo 调查发现,具有正常的脉冲星周期,但其年龄和自转衰减辐射亮度尚不可用。因此,难以确定 3HWC J0630+186 和 PSR J0630+19 是否有关联。通过获得的FAST望远镜时间,在五个百米口径球面射电望远镜(FAST)观测周期中,我们获得了PSR J0630+19的后续定时观测,观测持续时间超过一年。从我们的脉冲星数据中分析,我们确定了更精确的位置并推导出参数。参数表明,它是一个年老的脉冲星,其能量损失太低,无法为3HWC J0630+186的极高能辐射供电。

英文摘要:

3HWC J0630+186 is one of the very-high-energy gamma-ray sources in the third High-Altitude Water Cherenkov (HAWC) catalog, its origin and source are, however, not clearly identified. The only possible associated source is PSR J0630+19 depart from the center of 3HWC J0630+186. A few TeV halos of pulsars are currently believed the most dominant TeV-PeV gamma-ray sources, and PSR J0630+19 was firstly discovered by Arecibo survey with normal pulsar period, but its age and spin-down luminosity are not available. It is then difficult to determine if 3HWC J0630+186 and PSR J0630+19 are associated or not. With the awarded telescope time in five-hundred-meter aperture spherical radio telescope (FAST) observing cycle, we have obtained the follow-up timing observations of PSR J0630+19 with observed duration more than one year. From our pulsar data analysis, we determined a more precise position and derived parameters via pulsar timing. The parameters indicate that it is an old pulsar with energy loss too low to power the very-high-energy emissions from 3HWC J0630+186.
