论文摘要
我们首次报告了2021年10月15日对木星对木星的光影闪光灯的检测。我们对闪光灯的临时解决的三波段观测可以研究其光学能量,而无需近似冲击亮度温度。撞击器的动能等效于大约两个兆塔的TNT,一个比先前检测到的闪光的数量级大,并且与1908年的Tunguska对地球的影响相当。此检测表明,图格乌斯卡(Tunguska)对木星对木星的影响大约每年发生,大约每年发生了两次大量的次数,比terrestion terrestige terrestim of terrestial terrestial terrestial terrestiant terrestial terrestial terrestial频率更高。观察到的闪光灯显示出一个单元的黑体光谱,有效温度约为8300 K,而无明显的时间变化,可能代表陆生图尔斯卡级超级玻璃体的常见辐射特征。
We report the detection of an optical impact flash on Jupiter on 15 October 2021 by a dedicated telescope, Planetary ObservatioN Camera for Optical Transient Surveys (PONCOTS), for the first time. Our temporally resolved three-band observations of the flash allowed investigations of its optical energy without the need for approximations on the impact brightness temperature. The kinetic energy of the impactor was equivalent to approximately two megatons of TNT, an order of magnitude greater than that of previously detected flashes on Jupiter and comparable with the Tunguska impact on Earth in 1908. This detection indicates that Tunguska-like impact events on Jupiter occur approximately once per year, two-three orders of magnitude more frequent than terrestrial impacts. The observed flash displayed a single-temperature blackbody spectrum with an effective temperature of approximately 8300 K without clear temporal variation, possibly representing common radiative features of terrestrial Tunguska-class superbolides.
