Abstract / Description of output
High spectral resolution (R~ 40000) and signal-to-noise ratio
observations of five high Galactic latitude early-type stars taken from
the Edinburgh-Cape (EC) Faint Blue Object Survey are presented. These
were required to complete a magnitude range-limited survey of young
B-type objects with 11 <V <15. Of the five stars, four were
rejected on the grounds that they are either subluminous (subdwarf or
horizontal branch), were part of a binary system or possessed colours
later than the (U-B) =-0.5 cut-off employed. The remaining star in the
data set, EC 19596-5356, is found to exhibit normal young B-type stellar
properties. A kinematic analysis reveals that an origin in the Galactic
disc appears likely for all the stars in the sample. Some statistics are
drawn about the number density of young stars in the Galactic halo.
