The true nature of the DBA star KPD 2146+4117.

BERGERON P., WESEMAEL F. and SAFFER R.A.

Abstract (from CDS):

A new optical spectrum and model atmosphere analysis of the cool DBA white dwarf KPD 2146+4117, discovered in the Kitt Peak-Downes colorimetric survey, shows that this star should be reclassified as a helium-strong subdwarf B star. The parameters we derive, Teff=34,300 K, logg=6.1, and logy=-1.0, place it squarely within the sample of such objects studied by R. A. Saffer and coworkers.
