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

Meteoroid Streams Sculpt the Inner Zodiacal Cloud
The Planetary Science JournalThe abundance of dust encountered by Parker Solar Probe in the inner zodiacal cloud exhibits persistent variability of ∼50% on timescales of its ∼100 day orbits.

How Long-lived Grains Dominate the Shape of the Zodiacal Cloud [PDF]
The Planetary Science JournalGrain–grain collisions shape the three-dimensional size and velocity distribution of the inner Zodiacal Cloud and the impact rates of dust on inner planets, yet they remain the least understood sink of zodiacal dust grains. For the first time, we combine

The Zodiacal Cloud Complex [PDF]
International Astronomical Union Colloquium, 1991 Abstract The physical properties of the interplanetary dust grains are, out of the ecliptic plane, mainly derived from observations of zodiacal light in the visual or infrared domains. The bulk optical properties (polarization, albedo) of the grains are demonstrated to depend upon their distance to the Sun (at least in a 0.1 AU to 1.7 AU range in ...

Dynamics of the Zodiacal Cloud [PDF]
Symposium - International Astronomical Union, 1992 Advances in infrared astronomy and in computing power have recently opened up an interesting area of the solar system for dynamical exploration. The survey of the sky made by The Infrared Astronomical Satellite (IRAS) in 1983 revealed the complex structure of the zodiacal dust cloud. We now know the inclination and nodes of the plane of symmetry of the

Disentangling the main populations of the Zodiacal Cloud from Zodiacal Light observations [PDF]
Earth, Planets and Space, 2014 Photometric surveys of the Zodiacal Light (ZL) already allowed to retrieve features of interplanetary dust space distribution and optical behaviour. Of the brightness “gathering” function dZ = D(α)/m along each line of sight (LOS), (α being the phase angle, m the subsolar distance of the LOS, D) the local scattering coefficient), two approximate values

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 ...

Dynamical Model for the Zodiacal Cloud and Sporadic Meteors [PDF]
The Astrophysical Journal, 2011 The solar system is dusty, and would become dustier over time as asteroids collide and comets disintegrate, except that small debris particles in interplanetary space do not last long. They can be ejected from the solar system by Jupiter, thermally destroyed near the Sun, or physically disrupted by collisions.

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.
