9315285 Hankins Although radio pulsars have been known for nearly three decades and have been attributed to rotating neutron stars for nearly that long, the mechanism producing the radiation is still poorly understood. Observational and theoretical studies will be conducted to distinguish which of several existing models for pulsar emission is correct. The theoretical studies will focus on the rapid fluctuations of the emission expected from various models with the goal of uncovering features which will distinguish among them. The theoretical predictions will be tested through observations with time resolution an order of magnitude better than has been achieved previously. ***

9315285汉金斯尽管射电脉冲星已经被知道了近30年，并被认为是旋转的中子星造成的，但产生辐射的机制仍然知之甚少。将进行观测和理论研究，以区分现有的几个脉冲星发射模型中哪一个是正确的。理论研究将重点放在各种模型预期排放量的快速波动上，目的是揭示它们之间的区别特征。理论预测将通过观测来验证，时间分辨率比之前实现的要好一个数量级。***
