Parkes observations for project P1099 semester 2021APRS_01

CU Virginis is the best-studied member of the class of stellar radio transients known as stellar pulsars. Its circularly polarised radio pulses are explained by a model, which has consequences for the frequency-time dependence, polarisation and spectra of the pulses which can be tested using the Parkes ultra-wide-bandwidth receiver system. We propose to perform these tests and to demonstrate that the Parkes telescope can be used to observe transient events on time scales of minutes to hours.

CU Virginis（室女座CU星）是恒星射电瞬变源（stellar radio transients）类别中研究最为透彻的成员，该类天体即恒星脉冲星（stellar pulsars）。其圆偏振射电脉冲可通过某一模型得到阐释，该模型针对脉冲的频率-时间依赖特性、偏振特性与频谱特征给出了可通过帕克斯超宽带接收系统（Parkes ultra-wide-bandwidth receiver system）进行验证的推论。我们计划开展上述验证工作，并证实帕克斯望远镜（Parkes telescope）可用于观测时长为数分钟至数小时的瞬变事件。
