JWST Reveals Varied Origins between Jupiter’s Irregular Satellites
The Planetary Science JournalWe report JWST NIRSpec (0.7–5.1 μ m) observations of eight Jovian irregular satellites across five orbital groups. We detect variation in the phyllosilicate content of the three largest members of the Himalia collisional family (Himalia, D ∼ 140 km ...

‘Life’ of dust originating from the irregular satellites of Jupiter
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT The irregular satellites of Jupiter produce dust particles through the impact of interplanetary micrometeoroids. In this paper, the dynamics of these particles is studied by both high-accuracy numerical simulation and analytical theory, in order to learn their transport, final fate, and spatial distribution.

Three-body capture of irregular satellites: Application to Jupiter [PDF]
Icarus, 2010 We investigate a new theory of the origin of the irregular satellites of the giant planets: capture of one member of a ~100-km binary asteroid after tidal disruption. The energy loss from disruption is sufficient for capture, but it cannot deliver the bodies directly to the observed orbits of the irregular satellites.

Debris Rings From Extrasolar Irregular Satellites [PDF]
, 2021 Irregular satellites are the minor bodies found orbiting all four Solar System giant planets with large semimajor axes, eccentricities, and inclinations. Previous studies have determined that the Solar System's irregular satellites are extremely collisionally evolved populations today, having lost ~99% of their initial mass over the course of hundreds ...

The long-term dynamics of the Jovian irregular satellites [PDF]
Astronomy & Astrophysics, 2011 Context. The dynamical region of the Jovian irregular satellites presents an interesting web of resonances that are not yet fully understood. Of particular interest is the influence of the resonances on the stochasticity of the individual orbits of the satellites, as well as on the long-term chaotic diffusion of the different families of satellites ...

Re-recognized universality of Kozai oscillation on three-body dynamics [PDF]
Proceedings of the Japan Academy. Series B, Physical and Biological SciencesIn 1962, Yoshihide Kozai reported his findings on the secular dynamics of asteroids moving in orbits with high inclination and eccentricity. In contrast to the classic understanding of the stability of planetary motion in the solar system, Kozai showed ...

Capture of Irregular Satellites during Planetary Encounters [PDF]
Astronomical Journal, 2007 More than 90 irregular moons of the Jovian planets have recently been discovered. These moons are an enigmatic part of the solar system inventory. Their origin, which is intimately linked with the origin of the planets themselves, has yet to be adequately explained.

Fusion of multi-source precipitation records via coordinate-based generative models [PDF]
Nature CommunicationsPrecipitation remains one of the most challenging climate variables to observe and predict. Existing datasets face intricate trade-offs: gauges are relatively trustworthy but sparse, satellites provide near-global coverage with retrieval uncertainties ...
