The boundary between a dust- free and a dusty region defines the sublimation wall. In the literature two models for the structure of the wall are used: a wall with a fixed sublimation temperature and a wall with a density-dependent sublimation temperature. In the former case, the wall is vertical and in the latter, the wall is curved. We find important differences between these models’ SEDs in the wavelength range from 3 to 8 μm, the emission of the former being larger than that of the latter model. We quantify the differences in IRAC colors when these models are used to explain the observations. In the IRAC color-color diagram ([3.6]–[4.5] vs. [5.8]–[8.0]), the models are located in specific regions, either depending on the inclination, the mass accretion rate, or the model used. 2013 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57126152005 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.49 |
