Descripción
We present follow-up spectroscopy to 12 candidate white dwarf-brown
dwarf binaries. We have confirmed that 8 objects do indeed have a white
dwarf primary (7 DA, 1 DB) and two are hot subdwarfs. We have determined
the Teff and log g for the white dwarfs and subdwarfs, and
when combining these values with a model spectrum and the photometry, we
have 3 probable white dwarf-substellar binaries with spectral types
between M6 and L6.
