Description
Accurate knowledge of the amount of interstellar extinction and its properties are crucial to determine stellar masses and ages and to understand the star formation mechanisms. This can be challenging for young clusters such as NGC6530, hosted by the Lagoon Nebula, a very complex HII region illuminated by many O and B-type massive stars of the cluster. A detailed study on the complex dynamics of the gaseous component of this nebula, based on spectroscopic data of the Gaia-ESO Survey, has been very recentely presented by Damiani et al. (2017). We present the analysis of the stellar component observed with GES focusing on the reddening properties of members and non-members. We show that the reddening of the two stellar samples shows a spatial pattern that allows us to trace the nebular tridimensional structure of the dust component. We discuss the connections between the stellar population and the physical properties of the surrounding nebula through its gas and dust components.
