A Comparison of Radio-Frequency and Optical Studies of Selected Planetary Nebulae
Abstract
The thermal radio-frequency emission, Ev , per unit volume per unit frequency interval may be computed (e.g. from equations given by Oster) and compared with the volume emissivity E(Hβ) in the optical Hβ transition.
