Physical parameters and models of the ZL The variables of interest in the interplanetary medium are the number density, size, shape and albedo of the particles, their distance from the Sun, and their speed and direction of motion, almost all of which may be a function of any of the others. In addition, we would […]
Review of the period of my observations of the ZL, 1970-1974 It was the intention of this PhD study to fill in the gaps and uncertainties left in observational data in 1970; to make a comprehensive survey of a Doppler-modified Fraunhofer line in the ecliptic plane at all elongations from the Sun, and hence constrain […]
