Teff − log g-diagram. The helium main sequence (HeMS) and the EHB band (limited by the zero-age EHB, ZAEHB, and the terminal-age EHB, TAEHB) are superimposed with EHB evolutionary tracks from Dorman et al. (1993). The position of ASAS 10232 is indicated with a solid diamond. Open diamonds mark the position of other HW Vir-like systems (Charpinet et al. 2008; Drechsel et al. 2001; For et al. 2010; Geier et al. 2011b; Maxted et al. 2002; Klepp & Rauch 2011; Østensen et al. 2008, 2010; Wood & Saffer 1999; Almeida et al. 2012; Barlow et al. 2013).
