Abstract

We report recent observations of Achernar ($\alpha$~Eri) and its circumstellar environment obtained with interferometric and single-telescope techniques. We also briefly summarize the SIMECA modeling of the near-infrared polar envelope detected by interferometry around this star. From these results, the close environment of Achernar appears to be shaped at least by the fast stellar wind pushed by the von Zeipel effect and possibly by interactions between the two stars Achernar A and B.
