Poster title: Properties of massive stellar infalling envelopes

Abstract:
To achieve a better understanding of the high mass star formation, it is necessary to overcome several observational 
limitations, in particular when the incipient massive young stellar objects are deeply embedded in very dense envelopes. 
Fortunately, the availably of high sensitivity and angular resolution IR data provided by Herschel allowed us to select a 
sample of 60 objects. We constructed and modeled the SEDs, and derived properties of the envelopes. We find that they 
share similar trends with low mass stars, suggesting that both high and low mass stars may form in the same manner.
