Abstract:
The Rosette complex is a well studied region of the galactic plane
which presents the apparent characteristics of a triggered star forming
region. This is however still debated as no strong evidence corroborates
this statement. We focused on characterizing the young stellar population
in the Rosette to improve our understanding of the processes that regulate
the star formation in this region. We propose an original method relying
on the joint analysis of the star color and density in the near-infrared.
It yielded the identification of 13 clusters, 2 of them being new
discoveries. Based on their spectral index from UKIDSS K-band to WISE
W3-band, we identified 535 YSO candidates within these cluster boundaries.
