Spectroscopic pulsational frequency identification and mode determination of γ Doradus star HD 12901

Using multisite spectroscopic data collected from three sites, the frequencies and pulsational modes of the ? Doradus star HD?12901 were identified. A total of six frequencies in the range 12?d-1 were observed, their identifications supported by multiple line-profile measurement techniques and previously published photometry. Five frequencies were of sufficient signal-to-noise ratio for mode identification, and all five displayed similar three-bump standard deviation profiles which were fitted well with (l,m) = (1,1) modes. These fits had reduced ?2 values of less than 18. We propose that this star is an excellent candidate to test models of non-radially pulsating ? Doradus stars as a result of the presence of multiple (1,1) modes.
