Description


We present new high-dispersion spectroscopic and precise photometric observations to identify 11 new {gamma} Doradus variables. Seven of these new Doradus stars appear to be single, three are primaries of single-lined binaries, and one has two distant visual companions; none are double-lined or close visual binaries. Several of the stars show spectroscopic line-profile and low-amplitude radial velocity variability indicative of pulsation. All 11 stars are photometrically variable with amplitudes between 8 and 93mmag in Johnson B and periods between 0.398 and 2.454 days.
