摘要
We present our preliminary results of the IMF of the central star-forming cluster HD 97950 in NGC 3603 focussing particularly on low-mass regions. NGC 3603 is the best-studied template for extragalactic starbursts so far, and our recent high resolution data in the H and K bands have shown us the deepest sources in the cluster. The IMF have revealed the existence of low-mass stars down to 0.1 M-circle dot or even below, towards the hydrogen burning limit of 0.08 M-circle dot. The IMF continues to increase towards similar to 0.1 M-circle dot, but the flat slope indicates the significant deficiency of subsolar mass stars in the cluster core.
