Rotational modulation and single g-mode pulsation in the B9pSi star HD174356?
Original language description
Chemically peculiar (CP) stars of the upper main sequence are characterized by specific anomalies in the photospheric abundances of some chemical elements. The group of CP2 stars, which encompasses classical Ap and Bp stars, exhibits strictly periodic light, spectral, and spectropolarimetric variations that can be adequately explained by themodel of a rigidly rotating star with persistent surface structures and a stable global magnetic field. Using observations from the Kepler K2 mission, we find that the B9pSi star HD174356 displays a light curve variable in both amplitude and shape, which is not expected in a CP2 star.
