Abstract
In this paper the spectrophotometric and photometric data obtained for the sgB[e] star MWC 314 and the cPNB[e] star OY Gem during 2001–2004 at the high-mountain Assy-Turgen observatory are given. In the spectrum of MWC 314 the Hα, Hβ, He I and numerous Fe II intensity lines and the forbidden [N II] and [O I] lines are present. A variation in the intensity of the Hα lines relative to the continuum (from 24 to 33) is observed. During this time the equivalent width (EW) of the Hα line was changed in the limits 138–178Å,and the brightness magnitudes in the ranges V=9.82−9.96, B−V=1.77−1. 82 and V−R=1.53−1.64. The EW of the Hα is related to the star’s colour index B−V; as the EW increases, the B−V colour index is increased. In the spectrum of OY Gem the Hα, Hβ, He I and numerous Fe II intensity lines and the forbidden [Fe I], [N II], [O I], [O II], [O III] and [S II] lines are present. A variation in the intensity of the Hα lines relative to the continuum (from 100 to 138) is observed. During this time the EW of the Hα line was changed in the limits 700–955 Å,and the brightness magnitudes in the ranges V=11.05−11.36, B−V=0.32−0.38 and V−R=0.70−1.10. No correlation between the brightness V with either the colour indices or the EW of the Hα has been observed.
