HD 207331 a new δ Scuti star in the Cygnus field: discovery and follow-up observations
Abstract
Preliminary results on the discovery and follow-up observations of a new δ Scuti pulsator in the Cygnus field are presented. The variability of the star HD 207331 was detected while testing a Str\"omgren spectrophotometer attached to the H.L. Johnson 1.5-m telescope at the San Pedro M\'artir observatory, M\'exico. CCD photometric data acquired soon after confirmed its variability. A few hours of uvby differential photoelectric photometry during three nights revealed at least two beating periods. A two-site observational campaign carried out during one week in 2009 confirms the multi-periodic nature of this new δ Scuti pulsator.
