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.

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.

Spectroscopic Links among Giant Planet Irregular Satellites and Trojans
The Planetary Science Journal, 2023 We collect near-infrared spectra (∼0.75–2.55 μ m) of four Jovian irregular satellites and visible spectra (∼0.32–1.00 μ m) of two Jovian irregular satellites, two Uranian irregular satellites, and four Neptune Trojans.

Debris rings from extrasolar irregular satellites
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT 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 per cent of their initial ...

NEOWISE: OBSERVATIONS OF THE IRREGULAR SATELLITES OF JUPITER AND SATURN [PDF]
The Astrophysical Journal, 2015 We present thermal model fits for 11 Jovian and 3 Saturnian irregular satellites based on measurements from the WISE/NEOWISE dataset. Our fits confirm spacecraft-measured diameters for the objects with in situ observations (Himalia and Phoebe) and provide diameters and albedo for 12 previously unmeasured objects, 10 Jovian and 2 Saturnian irregular ...

CAPTURE OF IRREGULAR SATELLITES AT JUPITER [PDF]
Astrophysical Journal, 2014 The irregular satellites of outer planets are thought to have been captured from heliocentric orbits. The exact nature of the capture process, however, remains uncertain. We examine the possibility that irregular satellites were captured from the planetesimal disk during the early Solar System instability when encounters between the outer planets ...
