A Proposal for a 1-day Joint Discussion on:

               Pre-Solar Grains as Astrophysical Tools

This is jointly supported by Commission 35 "Stellar Constitution",
Commission 34 "Interstellar Matter", and Commission 22 "Meteors, 
Meteorites & Interplanetary Dust ". The JD will be formally proposed by 
Division IV "Stars" and Division VI "Interstellar Matter". 
The proposal results from extensive discussions among the members 
of the Working Group on Abundances in Red Giants, a WG of Division IV.


Motivation
----------
	The identification and recovery of pre-solar grains in
meteorites has caused a revolution in stellar structure and 
nucleosynthesis calculations. Yet the extent of this revolution is 
still not as large as it could be. It is time for the broader 
stellar community to see the constraints that these dat aprovide, and 
a JD seems to be an excellent way to bring together the
communities working on stellar spectra, stellar interiors, meteorites,
and the interstellar medium.

Topics
------
        We intend the meeting will take place over one full day, in
four sessions, arranged as follows:

  Session 1: Introduction and Overview
  Coffee
  Session 2: Forming Grains
  Lunch
  Session 3: Measuring Grains
  Coffee
  Session 4: Pre-Solar grains and nucleosynthesis


Invited Talks
-------------
        we currently plan on having Invited talks of 20 -25 mins,
to allow for some contributed talks. Details will be decided
when we have the list of requested contributions. Listed below 
are the Invited Talk topics and suggested speakers. We have tried 
to strike a balance between youth and experience, country and gender,
with a minimum of speakers from the SOC!

Session 1
  Overview: Opportunities from Grains 
  Grain Measurements in Space and in the Lab 
  Abundances in Grains, Stars and the Galaxy 
Session 2
  Condensation of Grains 
  Mass-loss: the role of Grains 
  Life Story of a Grain: Formation to the Lab 

Session 3
  Recent results on IR Grain Spectroscopy 
  Nano-SIMS 
  RIMS 

Session 4
  Pre-solar grains and novae 
  Pre-solar grains and supernovae 
  Pre-solar grains and AGB stars  
  Overview: Agenda for the Future 

  We hope you will view this proposal favourably
