摘要: Abstract In this paper we collected almost all HAeBe stars known so far (253 sources in total) to photometrically study their infrared properties. The 2MASS, WISE, IRAS and AKARI data are employed make analyses. It is shown from several two-color diagrams that 1 µm 60 µm radiations circumstellar disks with the power law distribution play a very important role for excesses which much larger than ordinary Be stars. WISE diagram, (W2–W3) vs. (W1–W2), some show thermal emissions probably due dust surrounded enhanced PAH features at 3.3 11.3 µm. wavelength longer not influenced by disk, but mainly ISM surrounded.
