Mass – radius distribution for the rm-sdBVs (green), which includes the properties of BA09 (Van Grootel et al. 2008) and CS 1246 (Barlow et al. 2010). The BLAPs (blue) with available mass and radius measurements from Kupfer et al. (2019) and Bradshaw et al. (2024), along with the two classified here (ZTF-sdBV10 and ZTF-sdBV12) are plotted for comparison. Lines of constant log g are drawn with gray dashed lines. Histograms of the mass and radius distributions for both populations are included, above the corresponding axis, in their respective colors.
