Cas A meeting agenda so far

["Laming, John" <jlaming@ssd5.nrl.navy.mil>]

Dear All,

We hope everyone is making plans to visit NRL in a couple of weeks.
Directions are posted on the Cas A discussion website under Una's "VLP
Logistics" e-mail. The only thing I really need to add is for anyone driving
to NRL along I-295. If the traffic suddenly slows to 50 mph or below, watch
out for an unmarked police car on the shoulder with a camera and radar gun!
Martin Laming will have to escort the foreign nationals (Jacco Vink, Carles
Badenes, and Martin Pohl) into NRL, so it is probably best if we all drive
in together on Thursday morning. All US citizens and permanent residents 
can enter unescorted, though everyone must obtain a visitor's badge in
building 72 first, and should bring some proof of citizenship, whether US or
otherwise.

We want spend the first day at least discussing how to do the "core"
projects in our proposal, i.e. element abundances as a function of 
position, observational tests of nucleosynthesis and the explosion
asymmetry. This will involve discussion of shock velocities and radii to
constrain our SNR models, and some consideration of how to identify the most
promising spatial regions for detailed spectroscopic study.

On the second day we hope to get to things like how to interpret spectra
from the "jet" regions, and specific things we should be looking for. Also 
synchrotron emission and electron heating at shocks. The combination of
magnetic field inference from the width of the synchrotron rim and
measurements of the thermal electron temperature behind the blast wave could
be very interesting.

On Friday afternoon we should discuss our strategy for getting the work done

and published. There is probably significant benefit to getting something
that's relatively easy published quickly (before anyone else does it!).
Another important deadline should probably be to have results to present at
the HEAD meeting in September. 

A tentative agenda follows. Anyone who would like to give a short (10/15
min) presentation or stake a claim to a particular piece of data analysis
should contact Una and Martin, or send an e-mail to the VLP discussion
pages. Let us know also which day you think would be best for your
contribution. We have already asked a few people to give talks to bring
everyone up to date on the status of Cas A and relevant aspects of SNR
physics. Following the agenda is a list of possible projects to get people
thinking.
