Novel Insights on the Dust Distribution in the Zodiacal Dust Cloud from PSP/WISPR Observations at Large Elongations [PDF]

open access: goldThe Astrophysical Journal
The Wide-Field Imager for Solar Probe (WISPR) on the Parker Solar Probe (PSP) mission maps the brightness produced by the zodiacal dust cloud (ZDC) from an historically unprecedented viewpoint.

Structure of the zodiacal cloud: new analytical and numerical solutions [PDF]

open access: goldEarth, Planets and Space, 2014
Recent results of analytical and numerical modelling of the interplanetary dust (IPD) distribution are described. They have been obtained with a new techniques employing the continuity equation written in the space of orbital coordinates. A 3-D structure and the corresponding 2-D slices for the IPD cloud governed by the Poynting-Robertson drag are ...

The origin and evolution of the zodiacal dust cloud [PDF]

open access: green, 1992
The astrophysical importance of the zodiacal cloud became more apparent. The most useful source of information on the structure of the zodiacal cloud is the Infrared Astronomical Satellite (IRAS) observations. A substantial fraction of the extensive IRAS

The contribution of cometary dust to the zodiacal cloud

open access: yesPlanetary 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 ...

3.3 Can Short Period Comets Maintain the Zodiacal Cloud? [PDF]

open access: bronzeInternational Astronomical Union Colloquium, 1976
The combined effects of the Poynting-Robertson drag, collisions and sputtering are destroying the interplanetary dust cloud. The mass-losses estimated by different authors reveal great discrepancies. The estimations range from 1 t sec−1 (purely Poynting-Robertson loss) over some 10 t sec−1 given by Whipple (1967) to a value of 100 t sec−1 which is ...

COMETARY ORIGIN OF THE ZODIACAL CLOUD AND CARBONACEOUS MICROMETEORITES. IMPLICATIONS FOR HOT DEBRIS DISKS [PDF]

open access: bronze, 2010
The zodiacal cloud is a thick circumsolar disk of small debris particles produced by asteroid collisions and comets. Here, we present a zodiacal cloud model based on the orbital properties and lifetimes of comets and asteroids, and on the dynamical evolution of dust after ejection. The model is quantitatively constrained by IRAS observations of thermal

Formation, Structure, and Detectability of the Geminids Meteoroid Stream

open access: yesThe 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.
