Deep Impact as a World Observatory Event. Synergies in Space, Time and Wavelength

Proceedings of the ESO/Vrije Universiteit Brussel Conference held in Brussels, Belgium,
7-10 August 2006


In the context of NASA's Deep Impact space mission, comet 9P/Tempel1 has been
at the focus of an unprecedented worldwide long-term multi-wavelength
observation campaign. The comet was also studied through its perihelion
passage by various spacecraft including the Deep Impact mission itself, the
Hubble Space Telescope, Spitzer, Rosetta, XMM and all major ground-based
observatories in a wavelength band from the cm-wave radio astronomy to x-rays.


The purpose of this meeting was to bring together an audience of
theoreticians and observers -- across the electromagnetic spectrum and from
different sites and projects -- to make full use of the massive ground-based
observing data set. Synergy between the many data sets can only be achieved,
if observers share their data and arrive at a consistent interpretation. A
coherent presentation of all data sets in an open forum should allow the
theoreticians to fully appreciate all observational constraints on modelling
the cometary nucleus, the cometary gas, the cometary plasma,
the cometary dust, and the comet's surface and its activity.


This Proceedings book contains papers presented at the meeting in
oral or poster format. The organisation of the book, though not a faithful
record of the talks, closely reflects the structure of the Workshop, with
topics grouped by discipline. Unfortunately, several speakers
have not submitted their manuscript for publication.
