摘要
Using narrow-band indices observed with the Cambridge spectrophotometer and analysed using synthetic spectra computed from model atmospheres, the iron abundances of a further 120 evolved stars have been determined. The results compare well with those from high-dispersion spectroscopic analyses. A number of super-metal-rich stars have been isolated, including three high-velocity stars lying below the M67 subgiant branch in the H-R diagram. © Royal Astronomical Society.
