英文摘要	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 to make analyses. It is shown from several two-color diagrams that from 1 mu m to 60 mu m infrared radiations from circumstellar disks with the power law distribution play a very important role for infrared excesses which are much larger than that for ordinary Be stars. In the WISE two-color diagram, (W2-W3) vs. (W1-W2), some sources show thermal emissions probably due to dust surrounded and enhanced PAH features at 3.3 and 11.3 pm. In the wavelength longer than 60 mu m infrared radiations are not so influenced by the circumstellar disk, but mainly from the ISM surrounded. (C) 2015 Elsevier B.V. All rights reserved.
