Hertzsprung-Russell diagram for π Aquarii. The solid lines represent the evolutionary tracks of rotating stars with solar metallicity and ω = 0.8, as outlined by Georgy et al. (2013) and Granada et al. (2013), the dash magenta line has an initial M = 10.5 M_⊙. The filled red circle denotes the findings from this study. The filled blue circle indicates the luminosity and temperature derived from Zharikov et al. (2013), calculated using varying distances. The filled gray circle corresponds to data from Tsujimoto et al. (2023). The filled green circle corresponds to data from Hohle et al. (2010).
