Line identifications in silicon stras in the visual region

Abstract

We have analysed a group of four Silicon stars (HD 2950553=α Dor, HD 54118, HD 73340 and HD 153880) and the normal AiV star HD 135382, on the basis of Bosque Alegre spectrograms (42 A/ram) In the red reglón (λλ4800-6700). The purpose of the work was to provide an Identification list of all lines which could be distinguished in at least two silicon stars. We derived wavelenghts accurate to 0,2 A for 550 lines.
