Positions of the primary and the secondary stars of the binary system presented in this work, in the T_eff − log g plane, are presented as green circles. The values of T_eff and log g found in Kosakowski et al. (2023) for the same system are depicted as purple triangles. The other two pulsating WD in an eclipsing system found by Brown et al. (2023) are depicted as orange pentagons. The system found by Pyrzas et al. (2015) is depicted as a pink ×. The first confirmed pulsating WD in a double-degenerate eclipsing system from Parsons et al. (2020) is depicted as a blue square. 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. 2018; Lopez et al. 2021) are shown as grey dots and black diamond shapes, respectively. The ELMV found by Guidry et al. (2021) is not being depicted since its atmospheric parameters have not been determined. The empirical ZZ Ceti instability strip published in Gianninas et al. (2015) is marked with dashed lines.
