Photoionization model of Novae V5668 Sgr based on Optical Spectroscopic Observations at Bosscha Observatory

Abstract

Abstract Novae V5668 Sgr spectra that have been observed at Bosscha Observatory on June 12, June 23 and August 15, 2015 using the NEO-R1000 spectrograph attached to the C-11 telescope showed that it has been entered the nebular phase. We will present the results of photoionization modelling using CLOUDY from observations of the Novae V5668 Sgr. The results of this modelling show that the spectrum profile matches fairly to the observations. Emission line features such as Hα, [O I] λ 6300, 6364 Å, [O II] λ 7320 Å, [O III] λ 5007 Å, [N II] λ 5755 Å, and Fe II λ 4924, 5169, 5317, 6149 Å on the observed spectra are also well formed and represented by the model.
