Spectroscopic Pulsational Frequency Identification and Mode Determination of γ Doradus Star HD 12901
E. Brunsden, K. R. Pollard, P. L. Cottrell +2
Using multi-site spectroscopic data collected from three sites, the frequencies and pulsational modes of the γ Doradus star HD 12901 were identified. A total of six frequencies in…
Spectral matching for abundances and clustering analysis of stars on the giant branches of ω Centauri
Jeffrey D. Simpson, P. L. Cottrell, C. C. Worley
We have determined stellar parameters and abundances for 221 giant branch stars in the globular cluster ω Centauri. A combination of photometry and lower-resolution spectroscopy wa…
Spectroscopic Pulsational Frequency Identification and Mode Determination of Gamma Doradus Star HD135825
E. Brunsden, K. R. Pollard, P. L. Cottrell +3
We present the mode identification of frequencies found in spectroscopic observations of the Gamma Doradus star HD135825. Four frequencies were successfully identified: 1.3150 +/-…
Medium-resolution s-process Element Survey of 47 Tuc giant stars
C. C. Worley, P. L. Cottrell
Medium-resolution (R~6,500) spectra of 97 giant stars in the globular cluster 47 Tucanae (47 Tuc) have been used to derive the C and N abundance sensitive index, deltaC, and to inf…
