Stacking-up a few hundreds of short exposures in J and Ks spectral bands over a FoV of 10.9\"x12.3\" centered on the R136a1 stellar component, enabled us to carry a refined photometric analysis of the core of R136. We detected 1110 and 1059 sources in J and Ks images respectively with 818 common sources. Thanks to better angular resolution and dynamic range, we found that more th","authors_text":"A. Origne, C.
