International audienceAims:The aim of this work was to derive chemical abundances in 5 stars that were previously reported to be SRd variable stars from the halo population, and, in particular, to check if manganese does show significant underabundance in our program stars similar to that of TY Vir, first detected by Luck & Bond. Methods: Elemental abundances have been found through the LTE and NLTE analyses, applied to high-resolution (R˜50 000) spectra. Results: We have derived the abundances of 18 chemical elements in RX Vir, AB Leo, CK Vir, SV UMa, and TY Vir, and made the following conclusions. Conclusions: .RX Vir is a typical solar-like star. Its classification as a halo population SRd variable star should be ruled out. The rem...
