Multisite spectroscopic seismic study of the beta Cep star V2052 Oph: inhibition of mixing by its magnetic field
M. Briquet, C. Neiner, C. Aerts +29
We used extensive ground-based multisite and archival spectroscopy to derive observational constraints for a seismic modelling of the magnetic beta Cep star V2052 Ophiuchi. The lin…
Towards ensemble asteroseismology of the young open clusters Chi Persei and NGC 6910
S. Saesen, A. Pigulski, F. Carrier +71
As a result of the variability survey in Chi Persei and NGC6910, the number of Beta Cep stars that are members of these two open clusters is increased to twenty stars, nine in NGC6…
Spectroscopic determination of the fundamental parameters of 66 B-type stars in the field-of-view of the CoRoT satellite
K. Lefever, J. Puls, T. Morel +3
We aim to determine the fundamental parameters of a sample of B stars with apparent visual magnitudes below 8 in the field-of-view of the CoRoT space mission, from high-resolution…
Long-term photometric monitoring with the Mercator telescope. Frequencies and multicolour amplitudes of Doradus stars
J. Cuypers, C. Aerts, P. De Cat +21
Gamma Doradus stars are excellent targets for asteroseismology since the gravity modes present in these stars probe the deep stellar interiors. Mode identification will improve the…
Spectroscopic and photometric variability of the O9.5Vp star HD93521
G. Rauw, M. De Becker, H. van Winckel +7
The line profile variability and photometric variability of the O9.5 Vp star HD93521 are examined in order to establish the properties of the non-radial pulsations in this star. Fo…
Close-up of primary and secondary asteroseismic CoRoT targets and the ground-based follow-up observations
K. Uytterhoeven, E. Poretti, M. Rainer +13
To optimise the science results of the asteroseismic part of the CoRoT satellite mission a complementary simultaneous ground-based observational campaign is organised for selected…
