Discovery of the first Super-Lithium rich Beat Cepheid: V371 Per
  Four high-resolution spectra of the double-mode Cepheid V371 Per, obtained
for the first time, showed the presence of the abnormally strong Li I 6707.76 A
line. Our analysis of the light element abundances indicates that the star did
not go through the evolutionary dredge-up stage. Large distance from the
galactic plane and the low metallicity suggest that V371 Per may belong to the
thick disc (or to the halo) of the Galaxy, which is consistent with its low
metallicity [Fe/H]=-0.42 and the enhancement of the alpha- and s-elements
relative to iron. Line splitting is observed in one of the spectra, which can
be due to the non-radial pulsations.
