Noctilucent Clouds, Aurorae, Zodiacal Light

1975
In 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, 1994
The 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.

Mass loss rate of the zodiacal dust cloud

The Moon and the Planets, 1983
The mass loss rate of the zodiacal dust cloud near the Sun has been estimated on the basis of the orbital behaviour of circumsolar dust grains suffering sublimation. It is found that the solar dust ring located at 4 solar radii from the Sun, which consists of grains whose inward spiraling due to the Poynting-Robertson effect is stopped by the influence

Three-dimensional models of the zodiacal dust cloud: A comparative study

Icarus, 1986
Abstract 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 ...

Can short period comets maintain the zodiacal cloud?

2008
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 ...
