摘要:

伽利略号航天器上的PWS仪器观测到木星低频射电被伽利略卫星掩星的现象。我们表明,ExPRES(系外行星和行星射电辐射模拟器)代码准确地模拟了伽利略/PWS观测到的整个光谱范围内的掩星的时间发生。这验证了ExPRES代码。该方法可应用于编制JUICE绕月飞行科学操作计划。伽利略卫星上的等离子体波科学(PWS)仪器观测到木星低频射电辐射被伽利略卫星掩星。我们表明,EXPRES(系外行星和行星射电辐射模拟器)代码准确地模拟了伽利略/PWS观测到的整个光谱范围内的掩星的时间发生。这验证了ExPRES代码。除了支持科学观测的分析外,该方法还可用于编制JUICE月球飞越科学操作计划。

英文摘要:

Occultations of the Jovian low frequency radio emissions by the Galilean moons have been observed by the PWS instrument of the Galileo spacecraft. We show that the ExPRES (Exoplanetary and Planetary Radio Emission Simulator) code accurately models the temporal occurrence of the occultations in the whole spectral range observed by Galileo/PWS. This validates of the ExPRES code. The method can be applied for preparing the JUICE moon flyby science operation planning. Occultations of the Jovian low frequency radio emissions by the Galilean moons have been observed by the PWS (Plasma Wave Science) instrument of the Galileo spacecraft. We show that the ExPRES (Exoplanetary and Planetary Radio Emission Simulator) code accurately models the temporal occurrence of the occultations in the whole spectral range observed by Galileo/PWS. This validates of the ExPRES code. In addition to supporting the analysis of the science observations, the method can be applied for preparing the JUICE moon flyby science operation planning.
