利用笼形水合物捕获理论，我们讨论了伽利略探测器在新的扩展核心吸积行星形成模型（包括迁移和盘演化）框架内测量的木星大气中挥发物的富集情况。我们构建了一个自洽模型，其中木星形成过程中吸积的星子的挥发物含量是根据圆盘的热力学演化计算出来的。假设 CO2 : CO : CH4 = 30 : 10 : 1（与星际介质测量兼容的比率），我们表明，我们可以用与最近根据内部结构模型对地球上存在的重元素总量设定的约束相兼容的方式来解释挥发物的富集。
Using the clathrate hydrates trapping theory, we discuss the enrichments in volatiles in the atmosphere of Jupiter measured by the Galileo probe in the framework of new extended core accretion planet formation models including migration and disk evolution. We construct a self-consistent model in which the volatile content of planetesimals accreted during the formation of Jupiter is calculated from the thermodynamical evolution of the disk. Assuming CO2 : CO : CH4 = 30 : 10 : 1 (ratios compatible with interstellar medium measurements), we show that we can explain the enrichments in volatiles in a way compatible with the recent constraints set from internal structure modeling on the total amount of heavy elements present in the planet.
