Purpose of workshop: 
In the context of NASA's Deep Impact space mission comet 9P/Tempel1 has been at the focus of an un-precendented worldwide long-term multi-wavelength observation campaign. The comet has been studied through its perihelion passage by various spacecraft including the Deep Impact mission itself, HST, Spitzer, Rosetta, XMM and all major ground-based observatories in a wavelength band from the cm-wave radio astronomy to x-rays. For some “glossy-print” information please have a look to e.g. ESO's dedicated web-pages
The ground-based observing campaign has been also described in a recent Sciencepublication by 208 authors from 85 academic institutions around the world (link to pdf). 
To make full use of this data set a workshop bringing together observers across the electromagnetic spectrum and from different sites and projects is considered of great importance. Synergy between the different data sets can only be achieved, if observers share their data and arrive at a coherent interpretation. A coherent presentation of all data sets will allow the theoreticians to fully appreciate all observational constraints. 
Specific topics of this workshop: 
General Cometary Topics From Space & Ground: 
  • the cometary nucleus 

  • the cometary gas 

  • the cometary plasma 

  • the cometary dust 


    the cometary surface and its activity

Deep Impact Specific Questions

  • release of unprocessed primordial material from the formation period of the comet 

  • long-term effects from the impact 

  • understanding of global properties of the nucleus 

  • surface layering of the 9P/Tempel1 nucleus 

  • impact cratering 

  • understanding of cometary dust after deep impact 

  • understanding the processes in the gas coma 

  • ground support of space missions: complementarity and needs
