Abstract: | Nainital-Cape Survey was started with an aim to search for new rapidly oscillating Ap stars in the northern hemisphere. We
discovered one new mono-periodic roAp star HD 12098. The frequency separation of HD 12098 suggests a rotation period of 5.5
days for the star. We summarize here the observations of HD 12098 and briefly discuss the results of the multi-site observation
campaign organized to resolve the ambiguity in the determination of the rotation period of HD 12098. Other interesting results
like non-oscillating Ap stars discovered and two candidate stars in which roAp periodicity is seen but not confirmed are also
discussed. |
