摘要：
We present new near-infrared integral field spectroscopy and adaptive optics imaging of the nucleus of NGC 1068. Using the stellar CO absorption features in the H and K bands, we have identified a moderately extincted stellar core centered on the nuclear position and of intrinsic size similar to 50 pc. We show that this nuclear stellar core is probably 5-16 x 10(8) years in age and contributes at least 7% of the total nuclear luminosity of similar to 1 x 10(11) L..
