J/A+A/448/181       IR colours of AGB and post-AGB stars    (Groenewegen+, 2006)

The mid- and far-infrared colours of AGB and post-AGB stars. Groenewegen M.A.T. <Astron. Astrophys. 448, 181 (2006)> =2006A&A...448..181G
ADC_Keywords: Stars, giant ; Photometry, infrared ; Models, evolutionary Keywords: stars: circumstellar matter - stars: mass loss - stars: AGB and post-AGB Abstract: With the advent of space missions, like SPITZER and ASTRO-F, with sensitive detectors in the near- and mid-infrared covering a reasonable field-of-view and having a good spatial resolution it will be possible to detect individual AGB stars in Local Group galaxies. The filters used by these missions are non-standard and different from mission to mission. In this paper the colours of mass-losing AGB and post-AGB stars are calculated in the broad-band filters of the SPITZER and ASTRO-F missions, as well as Bessell V,I and 2MASS J,H,K to connect these results to existing ground-based data. The models are calculated for carbon- and oxygen-rich chemistry and cover different effective temperatures and dust compositions. Description: 36 files are available electronically, corresponding to Tables A1-A36 of the Appendix, in the sub-directory "apx"; these files were grouped in 4 different files, delaing with AGB and post-AGB stages, and in the filters of 2MASS JHK and SPITZER (mag1) and ASTRO-F (mag2) The original files have names of the type: MAGNITUDE[n]AB_C.DAT, where -- n=1 list the VI, JHK, IRAC, MIPS colours; -- n=2 the various ASTRO-F colours. -- A= chemical type and effective temperature: C2650, C3600, M0, M6, M10. -- B= dust type and composition: AMC, AMCSIC15, AlOx, dpmod60alox40, dpmod. -- C= AGB or pAGB. For C= AGB the first column list the mass loss rate; for C=pAGB the first column list the temperature at the inner dust radius. File Summary:

Global notes: Note (G1): Dust composition is defined as: -- For dust around O-rich stars AlOx = 100% Aluminium Oxyde (amorphous porous Al2O3), with optical constants from Begemann et al. (1997ApJ...476..199B) and assuming a condensation temperature of Tc=1500K. dpmod60alox40 = A combination of 60% AlOX and 40% Silicate (optical constants from David & Pegourie, 1995, Cat. J/A+A/293/833) and a assuming condensation temperature of Tc=1500K. dpmod = 100% silicate with Tc=1000K -- For dust around C-rich stars AMC = 100% AMC with a Tc of 1000K AMCSI15 = A Combination of 85% Amorphous Carbon (AMC) and 15% Silicon Carbide (SiC) with optical constants from, respectively, Rouleau & Martin (1991ApJ...377..526R) for the AC1 species and α-SiC from Pegourie (1988A&A...194..335P). A Rc of 1200K is adopted.
