Statistical properties of circumstellar envelopes around AGB stars are discussed on the basis of a WISE AGB catalog verified in this way. We cross-matched an AGB star sample with the WISE All-Sky Source Catalog and the Two Mircon All Sky Survey catalog. Infrared Space Observatory (ISO) spectra of a subsample of WISE AGB stars were also exploited. The dust radiation transfer code DUSTY was used to help predict the magnitudes in the W1 and W2 bands, the two WISE bands most affected by saturation, for calibration purpose, and to provide physical parameters of the AGB sample stars for analysis. Description: Synthetic photometry and input parameters for Orich and Crich AGB stars model grid. The model grid is generated by DUSTY code. Four parameters are set free to generate the model grid: stellar effective temperature; dust composition; temperature at inner boundary of dust envelope; optical depth. The ranges of the four parameters and fixed value of other input parameters could be found in the paper.

In O-rich AGB stars, X=silicate/(silicate+Al_2_O_3_); in C-rich AGB stars, X=AmC/(AmC+SiC) (AmC is amorphous Carbon) See paper for more details. -------------------------------------------------------------------------------- Acknowledgements: Jianhui Lian, ljhhw(at)mail.ustc.edu.cn ================================================================================ (End) Jianhui Lian [USTC, China], Patricia Vannier [CDS] 21-Feb-2014
