Impact Rates in the Outer Solar System
The Planetary Science Journal, 2023 Previous studies of cometary impacts in the outer solar system used the spatial distribution of ecliptic comets (ECs) from dynamical models that assumed ECs began on low-inclination orbits (≲5°) in the Kuiper Belt.

Properties of the Irregular Satellite System around Uranus Inferred from K2, Herschel, and Spitzer Observations [PDF]
, 2017 In this paper, we present visible-range light curves of the irregular Uranian satellites Sycorax, Caliban, Prospero, Ferdinand, and Setebos taken with the Kepler Space Telescope over the course of the K2 mission.

A REGION VOID OF IRREGULAR SATELLITES AROUND JUPITER [PDF]
The Astronomical Journal, 2008 An interesting feature of the giant planets of our solar system is the existence of regions around these objects where no irregular satellites are observed. Surveys have shown that, around Jupiter, such a region extends from the outermost regular satellite Callisto, to the vicinity of Themisto, the innermost irregular satellite.

IMPROVED INDOOR POSITIONING USING FINGERPRINT TECHNIQUE AND WEIGHTED K-NEAREST NEIGHBOUR [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023 Global Navigation Satellite Systems are not effective when there is no direct line of sight between the user and the satellites, such as indoor environments and dense urban areas. Today, location-based services are used significantly due to their utility

Ionospheric plasma irregularities studied with Swarm satellites [PDF]
E3S Web of Conferences, 2018 To study and characterise the ionospheric plasma irregularities at all latitudes, one can employ in-situ measurements by satellites in polar orbits, such as the European Space Agency’s Swarm mission. Based on the Swarm data, we have developed the Ionospheric Plasma IRregularities (IPIR) product for a global characterisation of ionospheric ...

Direct imaging of irregular satellite discs in scattered light [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Direct imaging surveys have found that long-period super-Jupiters are rare. By contrast, recent modelling of the widespread gaps in protoplanetary discs revealed by Atacama Large Millimetre Array suggests an abundant population of smaller Neptune to Jupiter-mass planets at large separations.

Determining Undersampled Coastal Tidal Harmonics Using Regularized Least Squares
Earth and Space Science, 2023 Satellite altimetry, which measures water level with global coverage and high resolution, provides an unprecedented opportunity for a wide and refined understanding of the changing tides in the coastal area.

Composition of Jupiter irregular satellites sheds light on their origin [PDF]
, 2017 Irregular satellites of Jupiter with their highly eccentric, inclined and distant orbits suggest that their capture took place just before the giant planet migration.

Multicolor Photometry of the Uranus Irregular Satellites Sycorax and Caliban [PDF]
, 2001 We report on accurate BVRI photometry for the two Uranus irregular satellites Sycorax and Caliban. We derive colours, showing that Sycorax is bluer than Caliban. Our data allows us to detect a significant variability in the Caliban's light-curve, which

Last giant impact on the Neptunian system. Constraints on oligarchic masses in the trans-Saturnian region [PDF]
, 2011 Stochastic impacts by large bodies are, at present, the usually accepted mechanisms able to account for the obliquity of the ice giants. We attempt to set constraints on giant impacts as the cause of Neptune's current obliquity in the framework of modern
