Abstract

We present an optical spectrum of the star V1648 Aql (IRAS19386+0155) obtained at the 6-m SAO RAS telescope with a spectral resolution of R ≥ 60 000. Heliocentric radial velocity was measured from numerous metal absorptions is Vr = 10.18 ± 0.05 km s-1 (VLSR = 18.1 km s-1). We determined the atmospheric, circumstellar, and interstellar components in the profile of the Na I D lines at Vr = 9.2, -3.4, and -12.8 km s-1 respectively. The averaged over 20 identified DIBs velocity Vr = -12.5 ± 0.2 km s-1 coincides with the interstellar Na I component. Weak emissions with an intensity of about 10% of the local continuum level were detected in the spectrum; they are identified as low-excitation metal lines. Their central position, Vr = 8.44 ± 0.28 km s-1, points to the presence of a weak velocity gradient in the upper layers of the stellar atmosphere. Based on the spectroscopic data and taking into account the interstellar and circumstellar reddening, we estimated the star’s luminosity MV ≈ -5m and also obtained the lower estimate of distance d ≥ 1.8 kpc. Using the model atmosphere method, we determined the fundamental parameters and chemical abundances in the atmosphere confirming the status of a post-AGB star for V1648 Aql.
