T_eff − log g plane showing the positions of the three new pulsating WDs identified in this work, with atmospheric parameters from this study marked by × symbols. For comparison, atmospheric parameters from Kleinman et al. (2013) and Caron et al. (2023) are indicated by upside-down and right-side-up triangles, respectively. The known ZZ Ceti (Romero et al. 2022) and ELMVs (Hermes et al. 2012, 2013a,b; Kilic et al. 2015; Bell et al. 2015, 2017; Pelisoli et al. 2018a; Lopez et al. 2021) are shown as grey dots and grey diamonds, respectively. The empirical ZZ Ceti instability strip published in Gianninas et al. (2015) is marked with dashed lines.
