Three-dimensional models of the zodiacal dust cloud: A comparative study
Icarus, 1986Abstract Several analytical presentations of the three-dimensional distribution of interplanetary dust have been derived in the literature from measurements of the zodiacal light such as fan, ellipsoid, sombrero, and multilobe models. To provide a basis for comparisons with infrared measurements these classical and some new optical approaches are ...

Out of ecliptic zodiacal cloud profile
Planetary and Space Science, 1983Abstract In a previous paper, Mujica et al (1980), the optical homogeneity of the medium in the ecliptic plane was established calculating, for the ecliptic, the density and scattering functions ρ(r) and σ(θ) respectively. Starting with these results, we attempt now to find the zodiacal cloud shape out of the ecliptic.

Dynamical Structure of the Zodiacal Cloud
1999Advances in infrared astronomy and computing power have made detailed study of the structure of the zodiacal cloud possible. An extremely complex cloud has been revealed, quite distinct from the smooth, rotationally symmetric structure assumed prior to the launch of IRAS.

Origins of the zodiacal dust cloud
Journal of Geophysical Research, 1963The total intensity of light scattered by interplanetary dust has usually been directly related to the dust mass lost because of the Poynting-Robertson effect. The scattered light intensity thus would appear to define a dust supply rate that must be maintained if the dust intensity is to remain constant. This work suggests that comets apparently cannot

Noctilucent Clouds, Aurorae, Zodiacal Light
1975In this chapter we shall be concerned with the group of luminous phenomena that take place partly in the high and highest layers of the Earth’s atmosphere—noctilucent clouds, luminous bands, and aurorae—and partly in interplanetary space—the Zodiacal Light.

On the stability of the zodiacal cloud
Earth, Moon, and Planets, 1994The Poynting-Robertson effect (P-R effect) (Robertson, 1937), (Klacka, 1992) is generally considered to be the real effect which influences the motion of interplanetary dust particles (IDPs) — meteoroids, in the Solar System. The most general case of the validity of the P-R effect requires that Eq. (120) (or, Eq.
