The MAIA candidate star HD 208727
HD 208727 is a suspected member of the enigmatic MAIA variables andshows the largest yet observed amplitude in light variation for any ofthe potential members. Proven beyond doubt pulsation would pose aserious problem for stellar modelling and opacities, because eitheropacity source for driving pulsation has to be a different or newidentified, yet unkown, pulsation mechanism. We conclude from ourinvestigation that rotation is a more likely explanation for the lightvariability of HD 208727.

Radial velocities. Measurements of 2800 B2-F5 stars for HIPPARCOS
Radial velocities have been determined for a sample of 2930 B2-F5 stars,95% observed by the Hipparcos satellite in the north hemisphere and 80%without reliable radial velocity up to now. Observations were obtainedat the Observatoire de Haute Provence with a dispersion of 80Ä,mm(-1) with the aim of studying stellar and galactic dynamics.Radial velocities have been measured by correlation with templates ofthe same spectral class. The mean obtained precision is 3.0 km s(-1)with three observations. A new MK spectral classification is estimatedfor all stars. Based on observations made at the Haute ProvenceObservatory, France and on data from The Hipparcos Catalogue, ESA.Tables 4, 5 and 6 are only available in electronic form at the CDS viaanonymous ftp to cdsarc.u-strasbg.fr or viahttp://cdsweb.u-strasbg.fr/Abstract.htm
