Abstract

Observational data on the nova remnant GK Persei and its environs at a variety of wavelengths are presented and discussed. The data suggest that the nova exploded into a circumstellar cloud whose mass is estimated to be several solar masses and whose mean diameter is several pc. Radio images of the nonthermal emission associated with the interaction of the nova ejecta with this material show a remarkable similarity to young SNR. A suggestion made by Bode et al. (1987) that the circumstellar cloud is the neutral remnant of a PN which occurred about 100,000 yr ago is examined in detail. It is concluded that this interpretation provides a remarkably consistent framework for the interpretation of all the data.
