A solar abundance study using recent Ti I oscillator strengths.
Abstract
Summary. The f-values measured by Kiihne et al. (1977) lead to a solar abundance of titanium, log eTi = 4.94 1 0.12 on the scale log eR = 12. Comparison with abundances following from two independent sets of f-values (Ellis, 1976; Whaling et al., 1977) shows basic consistency of absolute scales. The solar ratio Ti/Ca = 3.8 x 10-2(125%) matches that found in chondritic meteorites of types Cl or C2, but contrasts with other types. Further subjects of abundance analysis are the solar velocity field, constraints on departures from LTE, and the accuracy of the STFD oscillator strengths of Kurucz and Peytremann (1975). Key words: oscillator strengths - solar Ti abundance - solar atmosphere
