Spectrophotometry of nova Cygni 1975.
Abstract
During the period from October 2, 1975, to January 7, 1976, several spectra of Nova Cyg 1975 were recorded principally in the nebular stage. From the H-delta profile obtained with a dispersion of 20 A/mm, it is deduced that the envelope probably consists of two polar caps and two equatorial rings. The coronal lines identified include forbidden Fe X at 6374 A, forbidden Fe Xi at 7892 A, (probably) forbidden Ni XV at 8024 A, and also forbidden S VIII at 9911 A, which had been found in the spectrum of a solar eclipse in 1965.
