Query: Observational results for northern and southern (candidate) gamma
  Doradus stars   We report on observational results obtained for 78 objects originally
classified as bona-fide or candidate gamma Doradus stars. For the southern
objects, we gathered echelle spectra with the CORALIE spectrograph attached to
the Euler telescope in 1998-2003 and/or Johnson-Cousins B,V,Ic observations
with the MODULAR photometer attached to the 0.5-m SAAO telescope in 1999-2000.
For the northern objects, we obtained Geneva U,B,B1,B2,V,V1,G observations with
the P7 photometer attached to the 1.2-m MERCATOR telescope in 2001-2004. At
least 15 of our objects are binaries, of which 7 are new. For 6 binaries, we
determined the orbit for the first time. At least 17 objects show profile
variations and at least 12 objects are multiperiodic photometric variables. Our
results allow us to upgrade 11 objects to bona-fide gamma Doradus stars and to
downgrade 8 objects to constant up to the current detection limits. Mode
identification is still ongoing, but so far, only l = 1 and 2 modes have been
identified.
