Descripción
A theory is outlined for analyzing the observed mean Doppler shift of
Fraunhofer lines in the zodiacal light, assuming that the particle
distribution in terms of composition, size, and shape is constant
throughout the interplanetary medium. The theory is applied to the
observed Doppler shift of H-beta; the Doppler shift in and out of the
ecliptic plane for elliptical and circular orbits of the zodiacal dust
is calculated for several different density distribution functions. Mean
Doppler shifts and lines of equal Doppler shift on the sky are plotted
as a function of or for various values of different parameters. It is
found that the curves of the lines of equal Doppler shift for the same
distributions are symmetrical in the ecliptic plane and antisymmetrical
in the plane of the solar meridian, that the Doppler shift along the
solar meridian is zero for all distributions, and that the Doppler shift
is particularly sensitive to changes in the distribution of eccentricity
assumed for the dust.
