Sun global Alfvén resonance from decade-scale dynamics of N–S separated
fast solar wind
Abstract
The Sun reveals itself in the 386–2.439-nHz (1-mo–13-yr) band of polar
(φsun>|70°|) fast (>700 km
s^−1) solar wind’s decade-scale dynamics as a globally completely
vibrating/resonating magnetoalternator and not just a proverbial engine
anymore. Thus North–South separation of hourly-averaged, 1994–2008
Ulysses samplings of the <10 nT polar winds in
~1.6·10^7 –2.5·10^9-erg energies revealed
spectral signatures of a ≥99%-significant Sun-borne global differential
resonant activity, verified across disparate data. Confirming the
Alfvén’s view on a Sun globally resonating under its
Ps=~11-yr Schwabe mode, this Alfvén (a-mode) resonance
(AR) comprising Rossby-like r-modes and cavity-confined R-modes, is
governed by Ps at a remarkable ~25% field variance
northside, a ~9-yr degeneration of Ps at
~20% southside, and a ~10-yr
degeneration of Ps under equatorial mixing. While composing the
PG∈~(88–100-yr) Gleissberg cycle, the 9–10–11-yr
sector coupling also co-triggers AR, Pi=Ps/i, i=2…n, n ∈ א,
imprinted in the fast winds at least to the order n=100. The
overwhelming (anisotropy moderating) and deterministic (with
Φ>>12 fidelity) AR is accompanied by a most
useful symmetrical antiresonance, P(-), whose both N/S tailing harmonics
P(-)17 are the well-known 154-day Rieger period, from which the
couplings-freed Rieger resonance sprouts as wind’s own. Thus the Sun is
a typical, ~3-dB-attenuated ring system of
differentially rotating and contrarily vibrating conveyor belts and
layers, with a continuous spectrum of modes, patterns complete in both
parities, and resolution better than 81.3 nHz (S) and 55.6 nHz (N) in
lowermost frequencies (≲2μHz in most modes). Unlike a resonating car
engine that tries but fails to separate its fixed casing, the resonating
free Sun exhausts the wind in a shake-off alongside the rotational axis.
AR advances standard stellar models, agrees with laboratory experiments
for enhanced studies of the Sun interior and heliosphere, and can
explain the million-degree corona and solar abundance.
