gamma-ray双星的周期射电形态

Periodic radio morphology of gamma-ray binaries

Javier Moldón, Marc Ribó, Josep M. Paredes

摘要:

伽马射线双星使我们能够研究物理过程,如粒子加速到非常高的能量和伽马射线发射和吸收与周期性变化的几何配置。这些源产生放射性粒子的流出,其结构可以用甚长基线干涉测量术(VLBI)成像。我们研究了γ射线双星LS I +61 303和LS 5039的形态变化,发现了PSR B 1259 -63和HESS J 0632 +057的扩展发射。基于这些结果,我们已经建立了AU尺度上的伽玛射线双星的无线电发射的基本属性和行为,我们已经有助于找到所有这些都是共同的特点。在这里,我们提出了最相关的属性,每个源和一般性质的伽马射线双星,我们描述的影响,这些双星系统的性质。

英文摘要:

Gamma-ray binaries allow us to study physical processes such as particle acceleration up to very-high energies and gamma-ray emission and absorption with changing geometrical configurations on a periodic basis. These sources produce outflows of radio-emitting particles whose structure can be imaged with Very Long Baseline Interferometry (VLBI). We have studied the changing morphology of the gamma-ray binaries LS I +61 303 and LS 5039, and we have discovered the extended emission of PSR B1259-63 and HESS J0632+057. Based on these results, we have established the basic properties and behaviour of the radio emission of gamma-ray binaries on AU scales, and we have contributed to find characteristics that are common to all of them. Here we present the most relevant properties of each source and the general properties of gamma-ray binaries, and we describe the implications on the nature of these binary systems.
