Arons, Jonathan 95-28271 Dr. Arons plans to investigate the mechanisms of emission and transfer of radio radiation from rotation powered pulsars, carried out in such a manner as to yield results which can be tested by past, current and forthcoming observations, then subsequently used to probe the physical characteristics of these sources of low entropy power to the surrounding medium. The first investigation will be a study of the "core" radio emission, with attention primarily focused on the hypothesis that this component comes from maser emission formed within the pair creation zone just above a pulsar's polar cap. The second area of study will be into the physics of the "conal" component of pulsar radio emission, to be studied as a manifestation of the shearing, counterstreaming flow in the boundary layer between the closed and open field lines. The final area of study will be an investigation of the transfer of polarized radio radiation through the cyclotron resonant regions in the outer magnetosphere, in an attempt to account for the origin of elliptically polarized radio emission from pulsar magnetospheres and to use these data to probe the plasma and field configuration in the region where the rotational energy loss is developed. ***

Arons，Jonathan 95-28271 Arons博士计划研究来自旋转驱动的太阳能电池的无线电辐射的发射和传输机制，以产生可以通过过去，当前和即将到来的观测进行测试的结果，然后随后用于探测这些低熵功率源的物理特性到周围介质。 第一项调查将是对“核心”无线电发射的研究，注意力主要集中在假设这一组成部分来自脉冲星极帽上方的对创造区内形成的脉泽发射。 第二个研究领域将是脉冲星无线电发射的“锥形”部分的物理学，将作为封闭场线和开放场线之间边界层中剪切逆流的一种表现形式进行研究。 研究的最后一个领域将是调查极化无线电辐射通过外磁层回旋共振区的转移，试图解释脉冲星磁层椭圆极化无线电发射的起源，并利用这些数据来探测旋转能量损失区域的等离子体和场配置。 ***
