THE FLUCTUATIONS IN THE IRAS DISTRIBUTION

Odessa Astronomical Publications, 2017
The great fluctuations in the infrared sky are situated along the meridians of Universal Sky Net. It is related also to the large structures. So the edge of the zone of avoidance of galaxies over IRAS60 and IRAS100 for long extension coincides to the Γ-

Physical Modeling of the Zodiacal Dust Cloud [PDF]

Symposium - International Astronomical Union, 2001
This review is based on extensive work done in collaboration with N. Gorkavyi, J. Mather, and T. Taidakova, which aimed at physical modeling of the interplanetary dust (IPD) cloud in the Solar System, i.e., establishing a link between the observable characteristics of the zodiacal cloud and the dynamical and physical properties of the parent minor ...

Electromagnetic Effects on the Zodiacal Dust Cloud [PDF]

Symposium - International Astronomical Union, 1980
Electromagnetic effects on charged zodiacal dust particles were investigated. It can be shown that: 1) stochastic variations induced by electromagnetic forces are unimportant for the zodiacal dust cloud except for the lowest masses, 2) systematic variations in orbit inclinations are unimportant if orbital radii are larger than 10 A.U.

Spitzer’s Solar System studies of asteroids, planets and the zodiacal cloud [PDF]

Nature Astronomy, 2020
In its 16 years of scientific measurements, the Spitzer Space Telescope performed a number of ground-breaking infrared measurements of Solar System objects. In this second of two papers, we describe results from Spitzer observations of asteroids, dust rings, and planets that provide new insight into the formation and evolution of our Solar System.

SIRTF: A Unique Opportunity for Probing the Zodiacal Cloud [PDF]

International Astronomical Union Colloquium, 1996
AbstractThe Space Infrared Telescope Facility (SIRTF) is planned for launch by NASA in 2001 in a heliocentric orbit at 1.01 AU The spacecraft will drift away from the Earth slowly, reaching a distance of 0.3 AU behind the Earth at the end of its 2.5 year mission. This implies that SIRTF will spiral through the Earth's resonant dust ring (Wright et al.,

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform

Limnology and Oceanography: Methods, Volume 24, Issue 7, July 2026.
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

Stable Sediment Plumes Despite Tidewater Glacier Retreat in a South Greenland Fjord

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Tidewater glaciers play a critical role in ice sheet mass loss and fjord hydrography, as meltwater runoff volume and injection depth can influence sediment transport, fjord circulation, and fjord stratification. As tidewater glaciers retreat and transition from marine‐ to land‐terminating, the impacts of shifting meltwater delivery depth on ...

Temporal variation of the zodiacal dust cloud [PDF]

Monthly Notices of the Royal Astronomical Society, 2001
ABSTRA C T A Markov chain model is constructed to investigate fluctuations in the mass of the zodiacal cloud. The cloud is specified by a three-dimensional grid, each element of which contains the numbers of dust particles as a function of semimajor axis, eccentricity and mass. The evolutionary pathways of dust particles owing to radiation pressure are

Zodiacal Fluctuations Should Drive Inner-source Pickup Ion Variability

The Astrophysical Journal
Dust near the Sun is implicated in the production of an unexpected “inner source” of pickup ions (PUIs). Multiple mechanisms related to dust have been proposed to explain this phenomenon, and all depend on the amount, along with the spatial and size ...
