2168 20160706145718.0 DOI 10.1017/pasa.2014.20 ASTROimport-325 Davie, M. W. 2014 We present improvement and confirmation of identified frequencies and pulsation modes for the γ Doradus star HD 189631. This work improves upon previous studies by incorporating a significant number of additional spectra and precise determination of frequencies. Four frequencies were identified for this star: 1.6774 ± 0.0002 d-1, 1.4174 ± 0.0002 d-1, 0.0714 ± 0.0002 d-1, and 1.8228 ± 0.0002 d-1 which were identified with the modes (l,m) = (1, +1), (1, +1), (2, -2), and (1, +1) respectively. These findings are in agreement with the most recent literature. The prevalence of (l,m) = (1, +1) modes in γ Doradus stars is starting to become apparent and we discuss this result.
