Abstract

Abstract We present here our recent results concerning the shape of interstellar plasma spectrum of five pulsars: PSR 0329 + 54, 0437 − 47, 0809 + 74, 0950 + 08 and 1642 − 03 based on complex analysis of multi-frequency observations of diffractive and refractive scintillation of pulsars. We found that in particular directions, the spectrum differs from the Kolmogorov one. Strong angular refraction was detected in the direction to PSR 0329 + 54, 0437 − 47 and 0950 + 08.

来自多频脉冲星观测的星际湍流等离子体光谱

摘要本文基于对脉冲星衍射和折射闪烁多频观测的复杂分析，给出了5颗脉冲星PSR 0329 + 54、0437−47、0809 + 74、0950 + 08和1642−03星际等离子体光谱形状的最新研究结果。我们发现，在特定的方向上，光谱与Kolmogorov谱不同。在PSR 0329 + 54、0437−47和0950 + 08方向检测到强烈的角折射。
