摘要：

We present a near-infrared K-n-band photometric study of edge-on galaxies with a box/ peanut-shaped 'bulge'. The morphology of the galaxies is analysed using unsharp masking and fits to the vertical surface brightness profiles, and the results are compared to N-body simulations and orbital calculations of barred galaxies. Both theoretical approaches reproduce the main structures observed.
