Popis | V2107 Cyg is located in the direction of Cyg OB1 stellar association. The eclipsing system consists of an early-B primary and a late-B type secondary component contributing about 6% of the total light. Line profile variability and photometry suggest strongly it is a beta Cep type non-radial pulsator. A signature of the faint secondary component is for the first time identified through spectra disentangling. |
