On the Formation and Extreme Rotational Angular Momentum of Jupiter: A Three-Tier Hierarchical Subsystem Accretion and Complete Angular Momentum Inheritance Model

English Description On the Formation and Extreme Rotational Angular Momentum of Jupiter: A Three-Tier Hierarchical Subsystem Accretion and Complete Angular Momentum Inheritance Model Jupiter possesses the largest mass and the most extraordinary rotational angular momentum among all planets in the Solar System (with a rotation period of only about 9 hours and 55 minutes), while maintaining an exceptionally stable axial tilt of 3.13 degrees. Conventional models proposed by the astronomical community—such as "direct nebular gas collapse" and "random orbital protoplanet impacts"—suffer from severe logical contradictions in classical and fluid mechanics. These models not only fail to explain the efficient accumulation of unidirectional angular momentum, but also rely on physically unsubstantiated ad-hoc patches like "magnetic braking" to correct computational failures. This paper proposes a novel "Three-Tier Hierarchical Subsystem Accretion Model." Rather than accreting gas directly from a diffuse nebula, proto-Jupiter utilized a hierarchical gravitational collection network—"Sub-sub-system → Sub-system → Jupiter's Main Body"—to first incubate multiple "Neptune-sized" giant prograde gas satellites within its sub-system, which were subsequently consumed one by one by Jupiter via spiral accretion. Key Theoretical Highlights: Uncontaminated Angular Momentum Living Fossil: Because this gravitational scavenger network thoroughly cleared its orbital feeding zone in the very early stages of evolution, Jupiter was spared from late-stage random impacts by rogue protoplanets, preserving pristine physical records from the birth of the Solar System. Lossless Angular Momentum Inheritance: Dual orbital rectification across the sub-sub-system and sub-system eliminated retrograde torque cancellation, transferring 100% prograde rotational and orbital angular momentum into Jupiter without requiring magnetic braking patches. Primordial Disk Parameter Inversion: Applying Newton's law of universal gravitation and the conservation of angular momentum, this model enables the direct inversion of the original total mass, orbital feeding zone width, and surface mass density of the early Solar System at Jupiter's orbit (approx. 5.2 AU). JWST Observational Predictions: Predicts verifiable signatures for the James Webb Space Telescope (JWST) in young galactic protoplanetary disks, including hierarchical circumplanetary disks, Neptune-sized protosatellites within disk gaps, and low-temperature "cold accretion" spectral profiles. 中文摘要 (Chinese Description) 論木星形成與極端自轉角動量之成因:三階層級次系統吸積與角動量完整繼承模型 木星擁有太陽系所有行星中最大的質量與最驚人的自轉角動量(自轉週期僅約 9 小時 55 分鐘),且自轉軸傾角維持在極度穩定的 3.13 度。過去天文學界提出的「星雲氣體直接坍縮」與「軌道原行星隨機撞擊」等模型,在經典力學與流體力學上存在嚴重的邏輯矛盾,不僅無法解釋單向角動量的高效累積,更必須依賴缺乏物理依據的「磁場煞車」補丁來修正計算錯誤。 本文提出一套全新的「三階層級次系統吸積模型」(Three-Tier Hierarchical Subsystem Accretion Model)。本模型指出,早期木星並非直接從零散星雲中吸積氣體,而是透過「次次系統(Sub-sub-system)→ 次系統(Sub-system)→ 木星本體」的層級重力收集網,先在次系統中孕育出多顆「海王星級」的巨型順向氣體衛星,再由木星本體逐一螺旋吸食。 核心理論亮點: 未受污染的角動量活化石: 由於這套重力清道夫系統在演化極早期便徹底清空了軌道物質,使木星免受後期失控原行星的隨機撞擊干擾,完整封存了太陽系誕生初期的原生態物理資訊。 角動量無損耗完整繼承: 透過次次系統與次系統的雙重軌道整流,消除了逆向力矩抵消,無需依賴磁場煞車補丁即可解釋木星的極速自轉與 3.13 度穩定軸傾角。 早期太陽星雲參數反演: 結合牛頓萬有引力定律與角動量守恆定律,可直接從木星現今數據反推出早期太陽系在木星軌道區域(約 5.2 AU)的原始總質量、軌道清空範圍與表面質量密度。 詹姆斯·韋伯望遠鏡(JWST)觀測預測: 預測 JWST 在銀河系年輕恆星系中將可觀測到多層級「環行星盤」結構、軌道環隙內的海王星級原生衛星訊號,以及低溫「冷吸積」光譜特徵。 Author: Pang-Chun Chao (趙邦俊)Contact: [email protected]: Creative Commons Attribution 4.0 International (CC BY 4.0)
