Photoelectric and CCD photometry of eclipsing contact binaries: UV Lyn, FU Dra and AH Aur
New photoelectric BV and CCD BVR observations of the eclipsing contactbinary systems UV Lyn, FU Dra and AH Aur obtained from January 2000 toApril 2001 are presented and analyzed. Photometric elements determinedfrom our light curves combined with published spectroscopic elementsyielded the absolute parameters of the systems. Analysis of the (O-C)diagram of AH Aur revealed fast period changes. The correct ephemerisfor the primary minimum was determined. The evolutionary status of allthree systems is discussed.

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
