A search for new gamma Doradus stars in the Geneva photometric database
Laurent Eyer, Conny Aerts
We present a study of selected potential gamma Doradus stars observed in the Geneva photometric system. Eleven stars were monitored at least during the last year of functioning of…
Prospects of Variable Star Research by Future Space Missions
Laurent Eyer
ESA and NASA are studying projects having a tremendous return on variable star research. Other national space agencies are also studying or developing projects of smaller costs but…
Predictions on the number of variable stars for the GAIA space mission and for surveys as the ground-based International Liquid Mirror Telescope
Laurent Eyer, Jan Cuypers
Future space and ground-based survey programmes will produce an impressive amount of photometric data. The GAIA space mission will map the complete sky down to mag V=20 and produce…
New gamma Doradus Stars from the Hipparcos Mission and Geneva Photometry
Laurent Eyer, Conny Aerts
A search for new gamma Dor stars was undertaken using the Hipparcos periodic variable star catalogue and the Geneva photometric database, leading to a list of 40 new candidates. We…
Problems encountered in the Hipparcos variable stars analysis
Laurent Eyer, Michel Grenon
Among the 17 volumes of results from the Hipparcos space mission, two are dedicated to variable stars. These two volumes arose from the work of two groups, one at the Geneva Observ…
