Photometric multi-site campaign on the open cluster NGC 884 I. Detection of the variable stars
S. Saesen, F. Carrier, A. Pigulski +62
CONTEXT: Recent progress in the seismic interpretation of field beta Cep stars has resulted in improvements of the physics in the stellar structure and evolution models of massive…
2006 Whole Earth Telescope Observations of GD358: A New Look at the Prototype DBV
J. L. Provencal, M. H. Montgomery, A. Kanaan +53
We report on the analysis of 436.1 hrs of nearly continuous high-speed photometry on the pulsating DB white dwarf GD358 acquired with the Whole Earth Telescope (WET) during the 200…
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…
GD 99 - an unusual, rarely observed DAV white dwarf
Zs. Bognár, M. Paparó, B. Steininger +1
New observations of GD 99 are analysed. The unusual pulsation behaviour, showing both long and short periods, has been confirmed. All the available periods show a grouping of short…
