Title: Probing the deepest inner of a massive star cluster in the making

Abstract: Stellar clusters are the birthplace of most stars. Yet we only have a poor understanding of the formation of the clusters and their evolution while being gas dominated. We propose deep GSAOI/GeMS Ks band imaging to complement already obtained HST J and H band data of the gas dominated massive young star forming region G286.21+0.17. With a total gas mass of 10^4 Msun and an infall rate of ~3.4*10^(-2) Msun/yr, the region is a still forming candidate to super–massive stars clusters like NGC 3603. The Ks band observations will provide the crucial long wavelength information, at the same spatial resolution as HST in the J band, to probe the most embedded parts of the core. This will in turn allow us to estimate the total mass of stars formed, to determine the disk frequency in such a young cluster and to provide an accurate measurement of the low-mass initial mass function.
