Analysis of MERCATOR data - Part II: variable A & F stars is of MERCATOR data - Part I: variable B stars

Contains fulltext : 36085.pdf (Publisher’s version ) (Open Access) For a few decades, a large international community is working at the development of stellar seismology, intending to open a new window on the structure and evolution of stars, with the necessary parallel development of new observational techniques, modeling tools and methods for diagnostics and interpretation. This new window is associated with new observables, characterizing the oscillations (frequencies, amplitudes, line profiles,...) which are sensitive to the stellar interior and thus very complementary with surface observables, associated to astrometry, spectropolarimetry or interferometry. We re-classified 31 variable B stars which were observed more than 50 times in the Geneva photometric system with the p7 photometer attached to the MERCATOR telescope (La Palma) during its first 3 years of scientific observations. HD 89688 is a possible beta Cephei/slowly pulsating B star hybrid and the main mode of the COROT target HD 180642 shows non-linear effects. The Maia candidates are re-classified as either ellipsoidal variables or spotted stars. Although the mode identification is still
