| Abstract: | We present the second part of the results of our work to investigate the atmospheric parameters and chemical composition of
southern-hemisphere Cepheids obtained by analyzing 24 spectra for eight bright Cepheids and three semiregular bright supergiants
taken with the 1.9-m telescope of the South African Astronomical Observatory. The chemical composition and atmospheric parameters
have been determined for S Cru, AP Pup, AX Cir, S TrA, T Cru, R Mus, S Mus, U Car, V382 Car, HD 75276, and R Pup. |
