Mesures de vitesses radiales. VIII. Accompagnement AU sol DU programme d'observation DU satellite HIPPARCOS
We publish 1879 radial velocities of stars distributed in 105 fields of4^{\circ} \times 4^{\circ}. We continue the PPO series \cite[(Fehrenbachet al. 1987;]{Feh87} \cite[Duflot et al. 1990, 1992 and 1995),]{Du90}using the Fehrenbach objective prism method.

Interstellar Extinction in the Dark Cloud Khavtassi 217 IN Cassiopeia
The Vilnius photometric system has been applied for the investigation ofinterstellar extinction in the area of dark cloud Khavtassi 217 inCassiopeia. On the ground of photoelectric photometry of 152 stars,their photometric spectral types, absolute magnitudes, color excesses,interstellar extinctions and distances were determined. The area isdivided into two regions with different extinction versus distance run.Distances of the dark clouds are determined.

Contributing factors to flux changes in nonradial stellar pulsations
The factors contributing to flux changes in nonradial stellar pulsationsare investigated under conditions applicable to a variety of pulsatingstar types by examining a linearized analytic representation of observedflux changes due to nonradial pulsations with mode indices (l,m).Histograms are presented, showing as a function of l, the relativeimportance of local temperature, geometry, pressure, and limb-darkeningvariations in contributing to nonradial flux changes. A procedure forthe comparison of observational light and color data with modelpredictions on an amplitude ratio versus phase difference plane isoutlined. Application of this procedure to data on Beta Cephei, 53Persei, Delta C Scuti, rapidly oscillating Ap, Cepheid, and ZZ Cetivariables stars is shown to agree with published data on these systems.
