卡西尼大结局前的土星千米辐射
The Saturnian Kilometric Radiation before the Cassini Grand Finale
摘要：
土星公里辐射（SKR）是从围绕克朗磁极的极光区辐射出来的，在电离层之上，直到几个行星半径。它直接与来自其他行星磁层（如地球和巨行星）的极光无线电发射进行比较。我们对SKR的了解依赖于旅行者号（1980年和1981年的飞越）和卡西尼号（20世纪90年代的远程观测）的远程观测，直到卡西尼号在2004年开始绕土星运行。从那时起，它一直被定期从大量的远程位置观察到，但也是第一次在地球以外的行星上进行原位观察。本文回顾了SKR平均远程属性的最新技术水平，在其源区域内的原位通行证带来的第一个见解，以及卡西尼大结局之前的一些遗留问题及其接近的极地轨道。
英文摘要：
The Saturnian Kilometric Radiation (SKR) is radiated from the auroral regions surrounding the kronian magnetic poles, above the ionosphere up to a few planetary radii. It directly compares to the auroral radio emissions emanating from other planetary magnetospheres such as the Earth and the giant planets. Our knowledge on SKR relied on remote observations of Voyager (flybys in 1980 and 1981) and Ulysses (distant observations in the 1990s) until Cassini started to orbit Saturn in 2004. Since then, it has been routinely observed from a large set of remote locations, but also in situ for the first time at a planet other than Earth. This article reviews the state of the art of SKR average remote properties, the first insights brought by in situ passes within its source region, together with some remaining questions before the Cassini Grand Finale and its close-in polar orbits.
