Irregular Layout for a Satellite’s Interferometric Array [PDF]
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 We address the optimization problem of antenna placement on satellite-mounted interferometric synthetic-aperture instruments. In classic designs, the antennas on satellites are aligned regularly on the satellite’s frame.

‘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.

Irregular fixation – II. The orbits of irregular satellites
Monthly Notices of the Royal Astronomical SocietyABSTRACT Irregular satellites (ISs) are believed to have been captured during the Solar system’s dynamical history and provide clues for the Solar system’s formation and evolution. ISs occupy a large fraction of the Hill sphere of their host planet and their orbits are highly perturbed by the Sun.

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.

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 ...

An Ultradeep Survey for Irregular Satellites of Uranus: Limits to Completeness [PDF]
Astronomical Journal, 2005 We present a deep optical survey of Uranus' Hill sphere for small satellites. The Subaru 8-m telescope was used to survey about 3.5 square degrees with a 50% detection efficiency at limiting red magnitude m = 26.1 mag. This magnitude corresponds to objects that are about 7 km in radius (assuming an albedo of 0.04).

The long-term dynamics of the Jovian irregular satellites [PDF]
Astronomy and 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 ...

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 ...
