Jovian pulsars — a new class of pulsars from a magnetar- & dwarf novae-type prebursting evolution of Jupiter's global decadal magnetoactivity since 1996

M. Omerbashich

Résumé

The decadal global magnetoactivity evolution profile that precedes short-burst pulses in magnetar 4U 0142+61 and superhumps (superoutbursts) in dwarf novae now also emerges from mean least-squares spectra of over 12 billion mission-integrated Galileo–Cassini–Juno 1996–2020 annual samplings of Jupiter ⪅8nT global magnetic field. The profile revealed the high-power pulsar nature of jupiters by temporally mapping hyperlow-frequency (<1μHz) systematic dynamics of the magnetospheric signature in the solar wind (Rieger-resonance band of 385.8–64.3 nHz, or ~0.3·10^9–3·10^9 erg energetic perturbations) used as a proxy of Jovian magnetoactivity expressed in mean least-squares spectral magnitudes as a novel method for measuring relative field dynamics. The magnetoactivity impressed entirely unto the solar wind and encompassed the well-known solar system-permeating ~154-day Rieger period and the first six harmonics. The statistical fidelity of the spectral peaks remained well within a very high (Φ≫12) range of 10^7–10^5, reflecting the signature’s completeness and incessantness. The magnetoactivity upsurge from spectral means that maintained a stunning ~20% field variance (total annual energy budget) began reformatting the signature around 1999, gradually transforming it into the anomalous state by 2002, as supported by an increased anisotropic splitting of spectral peaks. In contrast, a comparison against 2005–2016 Cassini global samplings revealed a calm Saturnian magnetoactivity at a low ⪅1% field variance except for every ~7.1 yrs when it is ⪅5%, possibly due to orbital–tidal forcing. While this discovery of Jovian pulsars as their new class calls for redefining pulsars, the discovery of a global pulsation profile of the magnetar–novae type in a planet requires beacon-orbiter missions to monitor Jupiter’s magnetoactivity and its disruption capacity to solar system infrastructure.
