摘要:

2014年11月,利用XMM-牛顿和LOFAR、LWA和Arecibo射电望远镜对原型模式转换脉冲星PSR B 0943 +10进行了新的同步X射线和射电观测。它们使我们能够更好地约束这颗脉冲星的X射线光谱和变化特性,并首次在X射线较暗模式下探测到X射线脉动。结合的时间和频谱分析表明,非脉冲非热发射,可能的磁层起源,脉冲热发射从一个小极冠存在于两个无线电模式,并在相关的方式变化。

英文摘要:

New simultaneous X-ray and radio observations of the archetypal mode-switching pulsar PSR B0943+10 have been carried out with XMM-Newton and the LOFAR, LWA and Arecibo radio telescopes in November 2014. They allowed us to better constrain the X-ray spectral and variability properties of this pulsar and to detect, for the first time, the X-ray pulsations also during the X-ray-fainter mode. The combined timing and spectral analysis indicates that unpulsed non-thermal emission, likely of magnetospheric origin, and pulsed thermal emission from a small polar cap are present during both radio modes and vary in a correlated way.
