Abstract:
New observations of Π Aqr in the optical and infrared (IR) region are presented. The effective temperature of Π Aqr is derived by comparing observed and computed fluxes in the optical region. No near-ultraviolet excess was found but a strong near-IR excess beginning ar λ 5000Å and extending to longer wavelengths was detected. Two separate IR excess emission peaks of variable strength have been distinguished.
