Reformulating the Solar Coronal Heating Problem / 太陽コロナ加熱問題の再定式化

Short Abstract The solar coronal heating problem remains one of the major unresolved questions in stellar astrophysics. While the solar photosphere has an effective temperature of approximately 6,000 K, the corona reaches temperatures exceeding one million kelvin. Conventional explanations based on magnetic reconnection, wave heating, and related mechanisms have achieved substantial progress, yet a unified account of the temperature inversion, localized energy concentration, particle acceleration, and high-energy emission remains incomplete. This study reformulates the coronal heating problem within the Black Hole Fractal Steady-State Universe / Dynamic Mass Flow (BFSSU/DMF) cosmological framework. Rather than treating the Sun as an effectively isolated system powered solely by internal nuclear processes, the Sun is interpreted as a node embedded within a hierarchical mass-energy flow, while the corona is regarded as a boundary region in which Dynamic Mass Flow may become observable through energy conversion, plasma activity, and particle acceleration. Within this interpretation, magnetic reconnection, wave heating, flares, and related processes are not rejected; instead, they are reinterpreted as possible local conversion mechanisms operating at the DMF boundary. The study further develops a quantitative verification strategy based on the coronal energy budget. An energy-mismatch index, chi = E_req / E_int,max , is introduced to compare the observationally required energy supply with conservative upper bounds on known internal energy sources, thereby providing explicit observational and falsification criteria for the hypothesis. The framework is further extended to particle manifestation, solar-wind acceleration, and the early stages of stellar formation. In particular, a corona-first hypothesis is proposed as a thought experiment in which a corona-like high-temperature plasma state may emerge during stellar formation before the establishment of a mature photosphere. The purpose of this work is not to claim that the BFSSU/DMF interpretation has been observationally established, but to provide a coherent, quantitatively testable alternative framework for investigating whether the solar corona may represent a boundary manifestation of hierarchical mass-energy flow.
