Parkes observations for project P888 semester 2015OCTS_BPSR_01

Erratically-emitting neutron stars like Rotating Radio Transients (RRATs), represent approximately 3% (and increasing) of radio-emitting pulsars as they are found via searches of archival and current pulsar surveys. The sporadic emission from these sources makes them difficult to study and nearly all information about the properties of the objects is the result of dedicated monitoring and timing programs at Parkes telescope. This project represents an effort to obtain accurate timing solutions and polarization profiles of a sample of sparse-emitting pulsars. We will monitor and time 6 sources to determine basic RRAT properties including spin period, spin period derivative, and polarization properties. Thus enabling us to identify physical causes for the extreme emission, enable high-energy follow-up observations, deduce how these pulsars are related to the general pulsar and magnetar populations, and explore the distribution of extreme radio intermittence in neutron stars.

像旋转射电暂现源（Rotating Radio Transients, RRATs）这类爆发无规律的中子星，在已发现的射电脉冲星中占比约3%且该比例仍在上升——这类天体均通过对档案及现有脉冲星巡天数据的搜索得以被发现。这类源的间歇性射电爆发使其研究难度极大，目前关于该类天体性质的几乎所有信息，均来自帕克斯望远镜开展的专门监测与计时观测项目。本项目旨在获取一批稀疏射电爆发脉冲星的精确计时解与偏振轮廓。我们将对6个源进行监测并开展计时观测，以确定RRATs的基本性质，包括自转周期、自转周期导数以及偏振特性。借此我们得以探明这类极端射电爆发的物理成因，为后续高能观测提供支持，厘清这类脉冲星与普通脉冲星及磁星种群的演化关联，并探索中子星极端射电间歇爆发的分布规律。
