Scientific paper

Multiwavelength observations of seven stellar objects with strong UV excesses are presented. The observations are IUE spectrophotometry, Stromgren Vuvby optical photometry, Johnson JHK infrared photometry, intermediate resolution optical spectroscopy, and in one case a CORAVEL radial velocity survey. Three of the objects are field subdwarfs (one of which is helium-rich) with z-distances of from -150 to -300 pc from the galactic plane. A fourth subdwarf belongs to a binary system at z of about -500 pc; the primary of this system is a red giant. The three other objects are normal gravity early-type stars which appear to be located far below the galactic plane. One of them (CPD-61 deg 455) would appear to be a massive binary at z of about -5.8 kpc, and might provide critical clues concerning the nature of high latitude B stars if orbital motion is confirmed by future work.
