Abstract
A star formation history (SFH) is the stellar record of the various processes that shaped a galaxy and star clusters since its birth to its current physical state. Studying the young open cluster NGC 2244, and in particular its massive stellar population, can improve our understanding of its formation mechanism, stellar evolution, feedback, and provide a basis for a better understanding of the formation of extragalactic star clusters. In this contribution, we present the first steps towards the derivation of the SFH of NGC 2244. We discuss the first results concerning the membership determination and the observed binary fractions of O- and B-type stars among NGC 2244. Finally, an overview of the forthcoming steps is also presented.
Keywords : Star Formation History, massive star, binary star
