ABSTRACTRankin, Joanna"Electrodynamics Through Subbeam Circulation Mapping"AST-9986754The PI proposes to investigate the hypothesis that pulsar subpulses contain structure that gives information on the spatial and temporal properties of the emitting region. Preliminary pseudo-maps of the emitting near-polar region have been constructed from pulse data for one pulsar (0031-07). An international collaboration involving collaborators in the U.S. and India will provide data on a number of additional pulsars. The intent is to establish whether the widely differing subpulses in other pulsars can be interpreted using this technique. The project will be conducted in collaboration with the Raman Research Institute in Bangalore, India.Funding for this project was provided by the NSF program for Stellar Astronomy & Astrophysics (AST/SAA) and the NSF International Program for Africa, Near East & South Asia (INT/India & Nepal).

Rankin，Joanna“Electrodynamics Through Subbeam Circulation Mapping“AST-9986754 PI提出研究脉冲星子脉冲包含发射区空间和时间特性信息的结构这一假设。 根据一颗脉冲星（0031-07）的脉冲数据，初步绘制了发射近极区的伪地图。 一项涉及美国和印度合作者的国际合作将提供一些额外的卫星数据。 其目的是确定是否可以使用这种技术来解释其他卫星中差异很大的子脉冲。 该项目将与印度班加罗尔的拉曼研究所合作进行，由美国国家科学基金会恒星天文学天体物理学计划（AST/SAA）和美国国家科学基金会非洲、近东南亚国际计划（INT/印度/尼泊尔）提供资金。
