New Emission Stars in B Cyg OB7

  • Published:
Astrophysics Aims and scope

This is a continuation of a search for and study of emission objects in known dark clouds and star formation regions. New results are presented from a search for emission stars in the region of Cyg OB7 where 36 new emission stars have been discovered previously. The current observations were made adjacent to previously studied regions in the vicinity of the object HH 448. 26 new emission stars were found in three small regions with a combined area of 0.11 sq. deg. On an (H-K)-(J-H) two-color diagram these stars lie among the classical T Tau stars (CTTS) and T Tau stars with weak lines (WTTS). A strong change in brightness was recorded for one of the emission stars.
