We present the results of simultaneous uvbyβ photometry carried out from 1999 to 2001 of the variable V2109 Cyg together with a spectroscopic analysis based on one high resolution spectrum obtained in 2000. From this study, the star is definitively classified as an evolved δ Sct-type variable with solar metal abundances. This conclusion is also...

We present the first results of a 2-year high-resolution spectroscopy campaign of 59 candidate $\gamma$ Doradus stars which were mainly discovered from the HIPPARCOS astrometric mission. More than 60% of the stars present line profile variations which can be interpreted as due to pulsation related to $\gamma$ Doradus stars. For all stars we...
