Description

π Aquarii is a bright, rapidly rotating classical Be star observed for over 100 years, exhibiting significant mid- and long-term variability. Here, we analyzed Hα profile variability over 23 years (2001-2023). We used the BeSOS and BeSS surveys. We utilized the ZPEKTR code, (based on TLUSTY models) for fast-rotating stars  to fit the HeI 4471 line. We used the BeAtlas grid, based on he HDUST code and considered a power-law for the density distribution in the disk to obtain the disk
parameters.
