Description

A simple analysis of five high-latitude blue stars with sharp spectral lines is presented. Reticon spectra at 30 A mm-1 and Stroemgren (uvby) photometry are used to determine Tsub(eff) and log g by the 'Kiel diagram' method and values of V sin i are estimated from the HeI lines. The results are checked by fitting models to the observed hydrogen line profiles. One star is probably an SMC supergiant, the other four appear to be population II stars, possibly related to the hot 'UV-bright' stars detected in some globular clusters. (author)
