Abstract (from CDS):

(ref???[q14])The light curve and spectra of Nova Centauri 1995 (V888 Cen) are analysed. The spectra were obtained a few days post-maximum. The nova is found to be a very fast nova, declining by 2mag within about 5±2d of maximum. The light curve shows strong oscillations in the transition region, of peak-to-peak amplitude about 1.5mag and period 12-15d. The light curve of Nova Centauri resembles closely that of Nova Aquilae 1918 (V603 Aql).

The early blue and red spectra obtained at Mt John show broad emission lines, many with P Cygni profiles. The absorption lines are found in two velocity systems at about -1765 and -3010km.s–1, in respectively the principal and diffuse-enhanced stages of spectral development, as defined by McLaughlin. Nova Centauri has many Feii lines in emission, indicating that it is a member of the Williams Feii class of classical novae.
