Location of RE 0503−289 (with its error ellipse) and related objects (Hügelmeyer et al. 2006; Kepler et al. 2016; Reindl et al. 2014b,a; Werner & Herwig 2006) in the log Teff – log g plane1. Evolutionary tracks for H-deficient (Althaus et al. 2009, full lines) and H-rich WDs (Miller Bertolami 2016, dashed lines) labeled with their respective masses in M⊙ are plotted for comparison. “Wind limits” of Unglaub & Bues (2000, their Figs. 6 and 13, digitized with Dexter2) are shown. The lines indicate for H-deficient stars A: so-called PG 1159 wind limit calculated with Ṁ = 1.29 × 10−15L1.86; B and C: photospheric carbon content is reduced by factors of 0.5 and 0.1, respectively; D: no PG 1159 star is known to the right of this line, and for H-rich stars E: wind limit; and F: He/H = 10−3 (by number).
