Search for Northern Hemisphere Rapidly Oscillating Ap stars
(< 8mmag) in the Johnson-B filter. More than a dozen roAp stars are multiperiodic, making them suitable for asteroseismology. The presence of high magnetic fields (of the order of few kG) in these stars gives us a chance to study the effects of magnetic fields on pulsations.
The thesis presents the efforts to search for new roAp stars in the northern hemisphere and its results.
