关于类星体非脉冲辐射的性质
On the nature of Off-pulse emission from pulsars
摘要：
在Basu等人的2011年研究中，我们报告了从两个长周期天体B 0525 +21和B2045-16中探测到的关脉冲发射。使用巨型米波射电望远镜（GMRT）的325 MHz频段在单个历元观测到了这些双星。在本文中，我们报告了一个详细的研究关闭脉冲发射从这两个天体使用多个观测在两个不同的频率，325 MHz和610 MHz波段的GMRT。我们报告在每次观测过程中检测到的非脉冲发射，并根据闪烁效应和非脉冲发射的光谱指数，我们得出结论的磁层起源。非脉冲发射的磁层起源引起了关于其发射机制的各种有趣的可能性，并提出了关于磁层结构的问题。
英文摘要：
In Basu et al. 2011 we reported the detection of Off-pulse emission from two long period pulsars B0525+21 and B2045-16. The pulsars were observed at a single epoch using the 325 MHz frequency band of the Giant Meterwave Radio Telescope (GMRT). In this paper we report a detailed study of the Off-pulse emission from these two pulsars using multiple observations at two different frequencies, 325 MHz and 610 MHz bands of GMRT. We report detection of Off-pulse emission during each observation and based on the scintillation effects and spectral index of Off-pulse emission we conclude a magnetospheric origin. The magnetospheric origin of Off-pulse emission gives rise to various interesting possibilities about its emission mechanism and raises questions about the structure of the magnetosphere.
