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 H, [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.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Emission lines,Optical spectroscopic,Photoionization models,Spectrum profile[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]We would like to thank The Ministry of Research, Technology and Higher Education for research grant through Simlibtabmas Program no 009/SP2H/LT/DRPM/2019. We thank support given by staff and techniciants at Bosscha Observatory of Institut Teknologi Bandung. We acknowledge with many thanks the light curve used in this research from AAVSO International Database contributed by world-wide observers. We are grateful to Professor Kawakita (Kyoto Sangyo University) for constant encouragement in spectroscopy with NEO-R1000, and Professor G. Ferland for the CLOUDY computer program that enable us to properly make photoionization model and spectral synthetic.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1755-1315/537/1/012004[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
