Fig. 7


Comparison of Teff for ZZ Ceti stars derived from near-UV spectra and compared with the optical determinations. Optical log g values are assumed in the determination of the UV temperatures. The size of the symbols reflects the different weights assigned to the UV spectra. The solid line represents a perfect match between UV and optical temperatures, while the dashed lines represent the ~350 K uncertainty allowed by the optical analysis. We rely on the ⟨3D⟩ (red filled circles), 1D ML2/α = 0.8 (black open circles), and 1D ML2/α = 0.7 spectra (blue open squares). This is an updated version of Fig. 8 from Tremblay et al. (2010).
