Photometric Survey of the Irregular Satellites [PDF]

Icarus, 2003
We present BVRI colors of 13 Jovian and 8 Saturnian irregular satellites obtained with the 2.56m Nordic Optical Telescope on La Palma, the 6.5m Magellan Baade Telescope on La Campanas, and the 6m MMT on Mt. Hopkins.

JWST Reveals Varied Origins between Jupiter’s Irregular Satellites

The Planetary Science Journal
We 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 ...

Three-Body Capture of Irregular Satellites: Application to Jupiter [PDF]

Icarus, 2009
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 3 $\mu$m Spectrum of Jupiter's Irregular Satellite Himalia [PDF]

The Astrophysical Journal, 2014
We present a medium resolution spectrum of Jupiter's irregular satellite Himalia covering the critical 3 $\mu$m spectral region. The spectrum shows no evidence for aqueously altered phyllosilicates, as had been suggested from the tentative detection of a

Photometry of Irregular Satellites of Uranus and Neptune [PDF]

The Astrophysical Journal, 2004
We present BVR photometric colors of six Uranian and two Neptunian irregular satellites, collected using the Magellan Observatory (Las Campanas, Chile) and the Keck Observatory, (Manua Kea, Hawaii).

Mapping the $\nu_\odot$ Secular Resonance for Retrograde Irregular Satellites [PDF]

, 2009
Constructing dynamical maps from the filtered output of numerical integrations, we analyze the structure of the $\nu_\odot$ secular resonance for fictitious irregular satellites in retrograde orbits.

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. Inspired by methods proposed for the placement of antennas in astronomical interferometers, such as ALMA or SKA, we explore irregular

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 ...

CAPTURE OF IRREGULAR SATELLITES AT JUPITER [PDF]

The 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 ...

Satellite image reconstruction from an irregular sampling [PDF]

2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
We propose a new method to solve a problem of image restoration with many different aspects: reconstruction from irregular samples, deconvolution and denoising. The model we propose is robust to different kind of noises, in particular, impulse and Gaussian noise. We compare our results to the ones obtained in [1] and show that our problem presents some
