An analysis of the spectra and light curve of Nova Centauri 1995

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 2 mag within about 5 +/- 2 d of maximum. The light curve shows strong oscillations in the transition region, of peak-to -peak amplitude about 1.5 mag and period 12-15 d. The Light curve of Nova C entauri resembles closely that of Nova Aquilae 1918 (V603 Aql). The early b lue and red spectra obtained at Mt John show broad emission lines, many wit h P Cygni profiles. The absorption Lines are found in two velocity systems at about -1765 and -3010 km s(-1), in respectively the principal and diffus e-enhanced stages of spectral development, as defined by McLaughlin. Nova C entauri has many Fe II Lines in emission, indicating that it is a member of the Williams Fe II class of classical novae.
