Spectroscopic monitoring of 10 new northern slowly pulsating B star candidates discovered from the HIPPARCOS mission

A one-year follow-up campaign of high-resolution, high-signal-to-noise spec troscopy for 10 candidate slowly pulsating B stars, which were discovered f rom the HIPPARCOS astrometric mission, shows that all stars exhibit line-pr ofile variability. From our data, and from the HIPPARCOS photometry, we con clude that all but one of the targets provide evidence of multiperiodicity, with periods of the order of days, confirming their pulsational nature. Th us they are confirmed slowly pulsating B stars. We summarize the pulsation periods and Q-values and select the most interesting targets for very-long- term follow-up observations with the goal of performing asteroseismology.
