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
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

Formation, Structure, and Detectability of the Geminids Meteoroid Stream
The Planetary Science Journal, 2023 The Geminids meteoroid stream produces one of the most intense meteor showers at Earth. It is an unusual stream in that its parent body is understood to be an asteroid, (3200) Phaethon, unlike most streams, which are formed via ongoing cometary activity.

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.

A Dust Detection Database for the Inner Heliosphere Using the Parker Solar Probe Spacecraft
The Astrophysical Journal Supplement Series, 2023 A database of in situ dust impact detections made by the Parker Solar Probe spacecraft is created to facilitate studies of interplanetary dust dynamics in the inner heliosphere.

Near-infrared Polarization Charateristics of the Zodiacal Light Observed with DIRBE/COBE
The Astrophysical Journal, 2023 We report near-infrared polarization of the zodiacal light (ZL) measured from space by the Diffuse Infrared Background Experiment (DIRBE) on board the Cosmic Background Explorer in photometric bands centered at 1.25, 2.2, and 3.5 μ m.
