Resumen:
In this contribution we present the Spectral Energy Distributions (SEDs) modeling of 4 massive stellar objects; in their initial evolutionary stages; obtained from the 1.2 mm catalogue of Beltran et al. (2006). The Herschel images at 70 - 500 µm; combined with those obtained by WISE; allow us to build the SEDs. We use the code of Whitney et al. (2003a) to model them. For the youngest objects; instead; we apply a simple modified black body model. We estimate the envelope circumstellar parameters which characterize these massive stars and identify the evolutionary stage of each object according to the sequence proposed by Chambers et al. (2009).
