Oral contributions that are not selected due to insufficient time slots, can be presented in poster format during the first poster session of the EWASS week (Monday to Wednesday); a short poster presentation in our special session is planned. For further information, please check for updates on our web-site, and do not hesitate to contact us at this e-mail address. On behalf of the Scientific Organizing Committee Rainer Spurzem, Seppo Mikkola

 Please also visis the webpages of two related special sessions, we coordinate our programs with their organisers:

Sp6: AGN, galaxy mergers, supermassive black holes and gravitational waves (PI Stefanie Komossa/Mauri Valtonen)
Sp10: Chemo-dynamical galaxy evolution (PI Gerhard Hensler)

The scientific rationale of our meeting:

Traditional Methods of stellar dynamics and celestial mechanics experience a revival due to modern supercomputers and astrophysical observations. Multi-Planetary Systems have been detected, exhibiting resonances, raising theoretical questions about their origin and stability. Dense star clusters, whether they are young clusters in our own galaxies, nuclear central star clusters with or without massive black holes in other galaxies are dynamically dominated by two-body relaxation, binaries, and possibly resonant configurations of black holes. In these session we want to bring together the cutting edge experts and promising young students and scientists in the fields of mathematical methods, high-accuracy numerical simulation and astrophysical observations - bridging the gaps between celestial mechanics and stellar dynamics from extrasolar planetary systems, through star clusters, to galactic nuclei with nuclear dense star clusters.
