How Long-Lived Grains Dominate the Shape of the Zodiacal Cloud
Planetary Science JournalAbstract Grain–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 collisional grooming method combined with a dynamical meteoroid model ...

Comet Fragmentation as a Source of the Zodiacal Cloud [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 Models of the thermal emission of the zodiacal cloud and sporadic meteoroids suggest that the dominant source of interplanetary dust is Jupiter-family comets (JFCs). However, comet sublimation is insufficient to sustain the quantity of dust presently in the inner solar system.

Collisional Evolution of the Inner Zodiacal Cloud
Planetary Science Journal, 2021 Abstract The zodiacal cloud is one of the largest structures in the solar system and strongly governed by meteoroid collisions near the Sun. Collisional erosion occurs throughout the zodiacal cloud, yet it is historically difficult to directly measure and has never been observed for discrete meteoroid streams.

IRAS Dust Bands and the Origin of the Zodiacal Cloud [PDF]
Highlights of Astronomy, 1989 AbstractPrevious discussions of the origin of the zodiacal cloud have attempted to distinguish between an asteroidal and a cometary source on the basis of collisional dynamics, that is, by calculating the rates of production and destruction of particles from the two possible sources.

A Survey of Radial Velocities in the Zodiacal Dust Cloud [PDF]
, 2007 This thesis documents the building of a pressure-scanned Fabry-Perot Spectrometer, equipped with a photomultiplier and pulse-counting electronics, and its deployment at the Observatorio del Teide at Izaña in Tenerife, at an altitude of 7,700 feet (2567 m), for the purpose of recording high-resolution spectra of the Zodiacal Light.

The Contribution of Cometary Dust to the Zodiacal Cloud
Planetary and Space Science, 1995 Abstract Any theory of the origin of the particles that supply the zodiacal cloud must account for two key, well-established observations. These are: (1) the observed plane of symmetry of the cloud; and (2) the observed shape of the cloud, that is, the observed variation of the flux in a given waveband with ecliptic latitude for a given elongation ...

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

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.
