Abstract
In the high resolution optical spectra we identified forbidden lines of [OI] and [CI], which indicate the presence of low excitation nebula. There are many emission lines due forbidden and permitted lines of neutral and singly ionised metals. The Hα, FeII 6383A, NaI D1, D2 lines and the Call IR triplet lines show P-Cygni profiles indicating a mass outflow. From the spectrum synthesis analysis of NI lines, we find the atmospheric parameters to be T ef f =8500K, log g=1.5, V turb =l3km s−1 and [Fe/H]=0.0. Carbon and nitrogen are found to be overabundant. From the analysis of Fe emission lines and forbidden lines, we derived T eri = 6100K±200 for the emission line region.
