HRD for stripped stars including objects discovered in this work and those from literature (Götberg et al. 2023; Ramachandran et al. 2023; Villaseñor et al. 2023; Irrgang et al. 2022; Bodensteiner et al. 2020a; Shenar et al. 2020a; Schootemeijer et al. 2018; Wang et al. 2021). Orange star symbols represent partially stripped stars, while blue are compact stripped He stars. The open star symbols denote low-mass stars in the subdwarf regime, while the filled ones correspond to intermediate masses. Blue stars with numbers 1−8, and 16 are stripped stars located in the Magellanic Clouds (Götberg et al. 2023), VFTS 291 is part of the LMC, and SMCSGS-FS 69 is in the SMC. The rest of the samples are Galactic sources. The evolutionary tracks in the background have the same meaning as in Fig. 15.
