    Abundances of Vanadium and Bromine in 3 Cen A: Additional Odd-Z Anomalies

    Full text link
    We report abundance excesses of 1.2 and 2.6 dex, respectively, for vanadium and bromine in the hot, peculiar star 3 Cen A. Abundances for these two odd-Z elements have not been previously reported for this star. Taken with previous work, they strengthen the case of the origin of the abundance peculiarities by diffusion.Comment: 4 Pages, 2 tables, 2 figures; accepted by Astronomy and Astrophysic
