Abstract

Abstract. In this study, we report on the occurrence of solar Type III radio bursts recorded by radio and plasma wave experiment (RPWS) experiment onboard Cassini spacecraft. This instrument is designed to investigate the Saturn's plasma environment and sub-auroral radio missions. RPWS/Cassini experiment allows to measure electric field over a frequency range from 1 Hz to 16 MHz (Gurnett et al., 2004). The essential observed emission is associated to the Saturnian Kilometric Radiation (SKR) which is generated in the sub-auroral regions of the magnetosphere. The capability of this experiment leads to detect Solar Type III radio bursts recorded during the increase phase of the solar activity, i.e. January 2008 to December 2014. Hence we have found more than 300 Type III solar bursts when the distance of Cassini to the Sun was about 10 AU. Observational parameters like the time occurrence, the emission frequency and the relative intensity are considered in this analysis. Those features lead us to characterize the detection conditions and to estimate the occurrence variabilities of Type III bursts.

Cassini/RPWS实验对太阳III型射电暴的观测

摘要在这项研究中，我们报道了卡西尼号宇宙飞船上的无线电和等离子体波实验（RPWS）记录的太阳III型射电暴的发生。该仪器旨在研究土星的等离子体环境和亚极光无线电任务。RPWS/Casini实验允许测量频率范围为1的电场 Hz至16 MHz（Gurnett等人，2004年）。观测到的基本发射与磁层亚极光区域产生的土星公里辐射有关。该实验的能力导致探测到在太阳活动增加阶段（即2008年1月至2014年12月）记录的太阳III型射电暴。因此，当卡西尼号与太阳的距离约为10时，我们发现了300多次III型太阳爆发 AU。本分析考虑了观测参数，如发生时间、发射频率和相对强度。这些特征使我们能够表征探测条件，并估计III型爆发的发生变化。
