We present ground-based high-resolution high S /N spectra of the slowly pulsating B star HD 147394. Two frequencies are clearly found in the moments of the Si II 4128-4130 doublet: f 1 = 0.8008 c d −1 and f 2 = 0.7813 c d −1. The frequency f 1 is also found in the HIPPARCOS data. A third frequency is also present in our spectroscopic data: f 3...

We analyzed the star HD 171219, one of the relatively bright Be stars observed in the seismo field of the CoRoT satellite, in order to determine its physical and pulsation characteristics. Classical Be stars are main-sequence objects of mainly B-type, whose spectra show, or have shown at some epoch, Balmer lines in emission and an infrared...
