我认为这是有问题的,虽然我们还没有一个确切的答案。我们通常认为木星有大约太阳能组成,根据太阳能丰富的测量(莉莲et al . 2009][1]意味着木星的总碳质量大约是10美元^{3}$木星的总质量。有大约0.3美元美元地球碳漂浮在木星的质量。接下来,我们需要知道这些东西在哪里漂浮。我们知道碳是漂浮在木星大气层(丰富)[2]相对于太阳能值约\ sim3美元的一个因素,纠正我们的总碳在木星的估计大约一个地球质量,如果木星是混合。这里的关键词是“混合”。如果在氢碳原子在解决高压力在木星的核心,然后不能形成钻石。只有一个(雨水冲洗类似于氦)[3]的相图(参见[氢和helium-mixtures][4])随后水滴或其他碳的积累可以形成,这将压制成钻石。然而目前的研究并不十分关注碳溶解在高压力,所以我不能引用任何可靠的碳会做什么。这样做的原因是,上述引用helium-rainout和[核心侵蚀][5]被认为是重要的。 I'll try and find some more sources on this as soon as I can go beyond the paywall to the research articles. **Comment on the high pressure-experiments and Juno:** To my knowledge carbon-hydrogen mixtures are not being looked at in the labs, but this knowledge might also be flawed. Juno will mostly be sensitive to Jupiter's density distribution at pressures up to ~1000 bars. Initial estimates show, that even if Jupiter has a dense, rocky core of 20 Earth masses, this will be barely visible in the data. To then filter out how much is carbon will be nigh-impossible with the current mission.
