Abstract

V 923 Aql is one of the candidateB E stars to be a binary star. In this research, optical and near-infrared spectral measurements of V 923 Aql is presented. V 923 Aql presents variable H Balmer line profiles with shell components. Hα profiles present R/V, E/C and radial velocity variation. Shell parameters of the envelope are calculated.
