Teff–﹩\mathrm{log}(g)﹩ diagram with evolutionary tracks of low-mass He-core pre-WDs as well as low-mass He-burning stars with hydrogen envelopes of 0.5, 2.0, and 4.0 × 10−3 M. The color coding of the tracks corresponds to the period of the fundamental radial oscillation mode. The inset shows a zoom-in around the location of high-gravity-BLAP-2 bounded by the black rectangle. Overplotted are the BLAPs and our stars color coded with the observed period, as well as the p-mode and g-mode sdB pulsators and the two known radial mode sdB pulsators: Balloon 090100001 and CS 1246.
