Secular Evolution of Disc Galaxies and of their Components
E. Athanassoula
I discuss several aspects of secular evolution linked to bars and to boxy/peanut bulges, based on a very large number of high resolution, fully self-consistent -body simulations…
Star cluster disruption by giant molecular clouds
M. Gieles, S. F. Portegies Zwart, H. Baumgardt +4
We investigate encounters between giant molecular clouds (GMCs) and star clusters. We propose a single expression for the energy gain of a cluster due to an encounter with a GMC, v…
K-Band Observations of Boxy Bulges. I. Morphology and Surface Brightness Profiles
M. Bureau, G. Aronica, E. Athanassoula +3
Kn-band images, unsharp-masked images, as well as major-axis and vertically- summed surface brightness profiles are presented for 30 edge-on spiral galaxies, most with a boxy or pe…
Unveiling the Boxy Bulge and Bar of the Andromeda Spiral Galaxy
Rachael L. Beaton, Steven R. Majewski, Puragra Guhathakurta +6
A new, 2.8 deg^2 J,H,K_s infrared survey from the 2MASS 6x program across the extent of the optical disk of the Andromeda (M31) galaxy provides a clear view of the M31 center almos…
On the origin of rR_1 ring structures in barred galaxies
M. Romero-Gomez, J. J. Masdemont, E. Athanassoula +1
We propose a new theory for the formation of rR_1 ring structures, i.e. for ring structures with both an inner and an outer ring, the latter having the form of ``8''. We propose th…
Barred Galaxies:Studying the chaotic and ordered nature of orbits
T. Manos, E. Athanassoula
The chaotic or ordered character of orbits in galactic models is an important issue, since it can influence dynamical evolution. This distinction can be achieved with the help of t…
