Radial-velocity determinations of six LMC superluminous giant candidates.
Abstract
Blue spectra at 121 Å mm-1 have been obtained for 12 candidate superluminous giant stars (SLGs) in ten clusters of the LMC. For ten of these stars, red spectra at 125 Å mm-1 were also obtained. Spectral classes are given for the 12 stars. Of the six measured for radial velocities, four are found to be foreground objects. The possibilities that all SLG stars are foreground objects or the combined light of more than one normal star are discussed.
