Binary system made up of two B-type stars 0.06-0.5" apart with an orbital period of 38.71 y (2010SerAJ.180...71C). A= 4.14V; B= 5.60V. Combined range given in the table. BCEP variations detected with two main groups of periods. The longer period variations might be SPB. Both objects might be variable. Detected periods for the shorter group are 0.191906, 0.170067 and 0.202065 d, and for the longer group, 0.34005, 0.43949 and 0.41108 d. |
