High Time Resolution Signatures of the Pulsar Radio Emission Mechanism

汉金斯，Timothy AST 96-18408博士。Hankins， Eilek和Weatherall将对脉冲星的射电发射机制进行观测和理论研究。研究人员将一个观测计划结合起来，其中包括超高时间分辨率脉冲星观测，以及由特定观测测试驱动的理论和数值分析和模拟。对几个明亮脉冲星的超高时间分辨率采样使他们能够区分无线电发射的特定模型。他们还将通过分析极帽的等离子体动力学来确定无线电噪声区的物理条件

Hankins, Timothy AST 96-18408 Drs. Hankins, Eilek, and Weatherall will carry out an observational and theoretical program of study into the mechanisms for radio emission from pulsars. The investigators combine an observational program which includes ultra-high time resolution pulsar observations with theoretical and numerical analysis and simulations that is driven by specific tests with observations. Ultra-high time resolution sampling of several bright pulsars allows them to discriminate between specific models for radio emission. They will also determine the physical conditions in the radio-loud region, through analysis of the plasma dynamics of the polar cap. ***
