High-resolution NIR and optical images are used to constrain a dynamical
model of the circumnuclear star forming (SF) region in the barred galaxy M100
(=NGC 4321). Subarcsecond resolution allowed us to distinguish important
morphological details which are easily misinterpreted when using images at
lower resolution. Small leading arms observed in our K-band image of the
nuclear region are reproduced in the gas flow in our model, and lead us to
believe that part of the K light comes from young stars, which trace the gas
flow.Comment: 2 pages, uuencoded compressed postscript file. To appear in: Spiral
