Global coupling mechanism of Sun resonant forcing of Mars, Moon, and Earth seismicity

2023-12-29T15:20:41+00:00

Global seismicity on all three solar system bodies with in situ measurements (Earth, Moon, and Mars) is mainly due to the mechanical Rieger resonance (RR) of macroscopic flapping of the solar wind, driven by the well-known P_Rg=~154-day Rieger period and commonly detected in most heliophysical data types and the interplanetary magnetic field (IMF). Thus, InSight mission marsquakes rates are periodic with P_Rg as characterized by a very high (≫12) fidelity Φ=2.8·10⁶ and by being the only ≥99%-significant spectral peak in the 385.8–64.3-nHz (1–180-day) band of highest planetary energies; the longest-span (v.9) release of raw data revealed the entire RR, excluding a tectonically active Mars. To check this, I analyzed the rates of the October 2015–February 2019, M_w5.6+ earthquakes, and all (1969–1977) Apollo program moonquakes. To decouple the magnetospheric and IMF effects, I analyzed the Earth and Moon seismicity during the traversals of the Earth’s magnetotail vs. IMF. The analysis showed with ≥99–67% confidence and Φ≫12 fidelity that (an unspecified majority of) moonquakes and M_w5.6+ earthquakes also recur at RR periods. Approximately half of the spectral peaks split but also into clusters that average into the usual Rieger periodicities, where magnetotail reconnecting clears the signal. Moonquakes are mostly forced at times of solar-wind resonance and not just during tides, as previously and simplistically believed. There is no significant dependence of sun-driven seismicity recurrence on solar cycles. Earlier claims that solar plasma dynamics could be seismogenic due to electrical surging or magnetohydrodynamic interactions between magnetically trapped plasma and water molecules embedded within solid matter or for reasons unknown are corroborated. This first conclusive recovery of the global coupling mechanism of solar-planetary seismogenesis calls for a reinterpretation of the seismicity phenomenon and reliance on global seismic magnitude scales. The predictability of solar-wind macroscopic dynamics is now within reach, which paves the way for long-term, physics-based seismic and space weather prediction and the safety of space missions. Gauss–Vaníček Spectral Analysis revolutionizes geophysics by computing nonlinear global dynamics directly (renders approximating of dynamics obsolete).

The Sun as a revolving-field magnetic alternator with a wobbling-core rotator from real data

2024-01-03T18:30:00+00:00

Rather than as a star classically assumed to feature elusive dynamo or a proverbial engine and impulsively alternating polarity, the Sun reveals itself in the 385.8–2.439-nHz (1-month–13-years) band of polar (φ_Sun>|70°|) wind’s decadal dynamics, dominated by the fast (>700 km s⁻¹) winds, as a globally completely vibrating revolving-field magnetic alternator at work at all times. Thus North–South separation of 1994–2008 Ulysses in situ <10nT polar-wind samplings reveals Gauss–Vaníček spectral signatures of an entirely ≥99%-significant, Sun-borne global incessant sharp Alfvén resonance (AR), P_i=P_S/i, i=2…n, i∈ℤ ∧ n∈א, accompanied by a symmetrical sharp antiresonance P^-. The ideal Sun (slow winds absent) AR imprints to the order u=136 into the fast winds nearly theoretically, with the northerly winds preferentially more so. The spectral peaks’ fidelity is very high (≫12) to high (>12) and reaches Φ>2∙10³, validating the signatures as a global dynamical process. The fast-wind spectra reveal upward drifting low-frequency trends due to a rigid core and undertones due to a core offset away from the apex. While the consequent core wobble with a 2.2±0.1-yr return period is the AR trigger, the core offset causes northerly preferentiality of Sun magnetism. Multiple total (band-wide) spectral symmetries of solar activity represented by historical solar-cycle lengths and sunspot and calcium numbers expose the solar alternator and core wobble as the moderators of sunspots, nanoflares, and coronal mass ejections that resemble machinery sparking. The real Sun (slow winds inclusive) AR resolves to n=100+ and is governed by the P_S=~11-yr Schwabe global damping (equilibrium) mode northside, its ~10-yr degeneration equatorially, and ~9-yr southside. The Sun is a typical ~3-dB-attenuated ring system, akin to rotating machinery with a wobbling rotator (core), featuring differentially revolving and contrarily (out-of-phase-) vibrating conveyor belts and layers, as well as a continuous global spectrum with patterns complete in both parities and the >81.3 nHz(S) and 55.6 nHz(N) resolution in lowermost frequencies (≲2 μHz in most modes). The global decadal vibration resonantly (quasi-periodically) flips the core, thus alternating the magnetic polarity of our host star. Unlike a resonating motor restrained from separating its casing, the cageless Sun lacks a stator and vibrates freely, resulting in all-spin and mass release (fast solar winds) in an axial shake-off beyond L1 at discrete wave modes generated highly coherently by the whole Sun. Thus, the northerly and southerly antiresonance tailing harmonic P^-₁₇ is the well-known P_Rg=154-day (or P_S/3/3/3 to ±1‰) Rieger period from which the wind’s folded Rieger resonance (RR) sprouts, governing solar-system (including planetary) dynamics and space weather. AR and its causes were verified against remote data and the experiment, thus instantly replacing the dynamo with a magnetoalternator and advancing basic knowledge on the >100 billion trillions of solar-type stars. Shannon’s theory-based Gauss-Vanicek spectral analysis revolutionizes astrophysics and space science by rigorously simulating fleet formations from a single spacecraft and physics by computing nonlinear global dynamics directly (rendering spherical approximation obsolete).

Two centuries-long mystery solved: the Sun acts as a magnetic alternator, not dynamo

2024-03-19T20:29:20+00:00

The most important discovery of 2023: an excentral wobbling core (really) runs the Sun and trillions of Sun-like stars. The Sun mimics ordinary rotating machinery.

Main takeaways

the study paints for the first time a complete picture of the macroscopic dynamics of the Sun (99.9% of the solar system's mass)
first-ever conclusive direct (from in situ data) detection of the solar core and its global dynamics
the core does not share a common center of mass with the rest of the Sun but lays instead off-center towards the south
the eccentric core then naturally wobbles once every ~2 years, causing the Sun to resonate like any operating motor engine
unlike engines firmly caged to prevent vibrational damage, the cageless Sun vibrates freely and completely
complete (including excess) global vibration consists indeed of constructive (resonance) and destructive (antiresonance) vibration
incessant vibration causes the Sun to (differentially) spin and emit its excess mass into space as the solar wind
the Sun's magnetic polarity reverses every ca. 11 years due to the wobbling core flipping under the global vibration
the Sun thus continuously behaves as an ordinary engine (revolving-field motor) rather than impulsively as an elusive dynamo
interior engine sparking manifests on the surface as sunspots; surface engine sparking—as nanoflares and explosions (CMEs)
explained the 154-day Rieger period in the solar wind's flapping, which dominates the solar system, e.g., causes seismicity
the discovery is in excellent agreement with sunspot historical records, remote data, and the experiment
the new result then instantly replaced the dynamo concept/models with the magnetic alternator from mechanical engineering
as based on verified reproducible computations from in situ/global data at highest energies, the results are conclusive/unquestionable
the new standard Sun applies to the >100 billion trillions of little-understood Sun-type stars (most, not counting dwarfs).
