“…A common method of data analysis applies forward calculations of the line of sight integral under reasonable assumptions about particle properties and spatial distribution. Detailed descriptions of the line of sight integrals have been given before (see Dumont, 1973;Röser and Staude, 1978;Giese et al, 1986). Also the average scattering properties of particles have been directly inverted from the brightness integral in some cases (see for instance Levasseur-Regourd and Dumont, 1980;Lamy and Perrin, 1986).…”

“…The spatial distribution of dust was derived from brightness data by several authors (see for instance Leinert et al, 1977;Lumme and Bowell, 1985;Murdock and Price, 1985;Giese et al, 1986;Good et al, 1986) and later on the distribution of orbital elements was given for several Zodiacal cloud models (see Kneißel, 1988). The concentration of the dust cloud towards the ecliptic plane yields a maximum in the distribution of orbital elements at small inclinations.…”

We discuss some aspects of the study of the Zodiacal cloud based on brightness observations. The discussion of optical properties as well as the spatial distribution of the dust cloud show that the description of the dust cloud as a homogeneous cloud is reasonable for the regions near the Earth orbit, but fails in the description of the dust in the inner solar system. The reasons for this are that different components of the dust cloud may have different types of orbital evolution depending on the parameters of their initial orbits. Also the collisional evolution of dust in the inner solar system may have some influence. As far as perspectives for future observations are concerned, the study of Doppler shifts of the Fraunhofer lines in the Zodiacal light will provide further knowledge about the orbital distribution of dust particles, as well as advanced infrared observations will help towards a better understanding of the outer solar system dust cloud beyond the asteroid belt.

“…On the basis of visible zodiacal light (ZL), many models have been constructed for the three dimensional distribution of dust particles in the zodiacal cloud (Giese et al (1986) and references therein). Although most models agree in that the density decreases by a factor of 2 within 0.2 to 0.3 AU above the Earth orbit (Giese and Kneißel, 1989), the resulting morphology of the isodensity contours in the helioecliptic meridian looks quite different from model to model.…”

We have calculated the brightness of zodiacal emission by using the three dimensional optical models of zodiacal cloud. By comparing the calculated brightness distribution with the IRAS observations, we found that the cosine model is the best out of the three for describing the helioecliptic latitude dependence of dust distribution. We also found best parameters for the heliocentric variations of the dust temperature and volumetric absorption cross-section. Inclination and ascending node of the symmetry plane were deduced from annual variations of i) the peak offset latitude and ii) the pole brightness difference. Longitudes of the ascending node derived from i) and ii) are shown to be significantly different from each other.

“…The brightness is roughly proportional to the dust cross sectional area per unit volume in space and stems predominantly from the mass range 10 −15 to 10 −8 kg [55] (radii 0.5 µm < a < 100 µm).…”

Cosmic dust particles are small solid objects observed in the solar planetary system and in many astronomical objects like the surrounding of stars, the interstellar and even the intergalactic medium. In the solar system the dust is best observed and most often found within the region of the orbits of terrestrial planets where the dust interactions and dynamics are observed directly from spacecraft. Dust is observed in space near Earth and also enters the atmosphere of the Earth where it takes part in physical and chemical processes. Hence space offers a laboratory to study dust plasma interactions and dust dynamics. A recent example is the observation of nanodust of sizes smaller than 10 nm. We outline the theoretical considerations on which our knowledge of dust electric charges in space plasmas are founded. We discuss the dynamics of the dust particles and show how the small charged particles are accelerated by the solar wind that carries a magnetic field. Finally, as examples for the space observation of cosmic dust interactions, we describe the first detection of fast nanodust in the solar wind near Earth orbit and the first bi-static observations of PMSE, the radar echoes that are observed in the Earth ionosphere in the presence of charged dust.
