Comparing peanut-shaped `bulges' to N-body simulations and orbital calculations
Source: Astrophysics and Space Science, Volume 284, Number 2, 2003 , pp. 753-756(4)
We present a near-infrared Kn-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.
