气态巨行星内部结构研究进展
Recent advances in the interior structure of the gas giants
摘要
Abstract
Jupiter and Saturn,as the gas giants of our solar system,account for over 90%of the total mass beyond the Sun and hold most of the system's angular momentum,playing a crucial role in the early history of the solar sys-tem.During their formation,these planets captured vast amounts of material from the protoplanetary disk.Their in-ternal structure and interior composition are fundamentally affected by material interaction,gravitational collapse,and subsequent long-term thermal evolution.Exploring the interior structure of the gas giants provides critical in-sights into several core questions in planetary sciences,including the conditions and evolutionary history of the pro-tosolar nebula,the formation and evolution mechanisms of solar system planets,and the interior structure and evolu-tion history of giant exoplanets.Furthermore,comparative studies between Jupiter and Saturn reveal important dif-ferences in their internal dynamics and evolutionary pathways,offering valuable benchmarks for understanding gi-ant planets both within and beyond our solar system.Current research on the interior structure of the gas giants primarily relies on external observational constraints such as gravity fields,magnetic fields,and atmospheric properties.However,inferring the interior structure from these constraints is inherently a highly degenerate inver-sion problem,depending on interior structural models,internal material properties,and calculations of planetary shape and gravity fields.Modern approaches increasingly integrate multiple physical constraints by combining gravity harmonics with magnetic field measurements and zonal wind profiles to reduce degeneracies in interior models.In recent years,the Juno and Cassini spacecraft have conducted close orbital explorations of Jupiter and Saturn,respectively,acquiring unprecedented high-precision gravity field data.Simultaneously,experimental and theoretical research on the physical properties of hydrogen and helium under extreme temperature and pressure conditions has achieved critical breakthroughs.With these in mind,this paper reviews the major exploration mis-sions for Jupiter and Saturn and elaborates on the core aspects of interior modelling,such as theoretical calcula-tions of planetary shapes and gravity fields,current knowledge of hydrogen/helium microphysical properties.The research progress on the internal structures of Jupiter and Saturn is also summarized,showing some representative frontier achievements.关键词
