Fig. 2.

Reduced TESS light curves of the pulsating pre-WD stars. The black dots are the TESS data sampled every two minutes. The blue lines are binned light curves that are calculated by a running mean every 20 points (corresponding to 38 minutes). K 1−16 was observed in eleven sectors (14, 15, 16, 17, 19, 20, 22, 23, 24, 25 and 26), HS 2324 was observed in two consecutive sectors (16 and 17), and the other stars were observed in a single sector each.
