P1057 - A study of unusual periodic fluctuations in radio pulsars

脉冲星是一种特殊的天体。有些突然变亮了几秒钟，几分钟，甚至更长时间。在大多数情况下，这些现象被认为是随机过程。然而，一些脉冲星会周期性地变亮。我们不知道为什么，我们也不知道为什么只有一些脉冲星这样做。这项提议的目的是监测周期性变亮的脉冲星，以确定这些特定脉冲星的特殊之处。许多理论模型试图解释这些现象，我们将使用这些观察结果来约束这些模型。

Pulsars are peculiar objects. Some suddenly brighten up for seconds, minutes or much longer. These phenomena are considered to be random processes in most cases. However, some pulsars brighten periodically. We do not know why, and we do not know why only some pulsars do this. The purpose of this proposal is to monitor pulsars which brighten up periodically bright in order to determine what makes these particular pulsars special. Lots of theoretical models try to explain these phenomena and we will use these observations to constrain these models.
