Parameters of eight planetary nebula nuclei
Abstract
Basic physical parameters of the nucleus and the radius of the envelope are estimated for eight planetary nebulae. In the luminosity-temperature diagram the eight objects are located in the initial part of the evolutionary track of planetary nebulae, indicating that they are relatively young.
