Abstract (from CDS):

We present the results of initial spectrographic followup with the Very Large Telescope (UT3, Melipal) for Ks >= 14 Galactic plane C IV emission-line candidates in the near-infrared (NIR). These seven faint stars all display prominent He I and/or C IV emission lines characteristic of a carbon-rich Wolf-Rayet star. They have NIR colours which are much too blue to be those of distant, classical WR stars. The magnitudes and colours are compatible with those expected for central stars of planetary nebulae, and are likely to come from massive progenitor populations. Our survey has identified thousands of such candidates.
