Description
The observations carried out with the coude spectrograph of the 2 m telescope and the main stellar spectrograph of the 6 m telescope have shown a short-periodic physical variability in α Cam (09.5 Ia), HD 188209 (09.7 IabN) and 68 Cyg (07.5 V). This variability complicates the search for relativistic companions in supergiant-''runaways'', but this one is of great interest due to possible causal relation to the stellar wind
