More interesting astrophysics, Oct 07-17

More interesting (to me) papers on astrophysics, collected between October 07 to 17th, 2008.

This is a mix of preprints (astro-ph) and fully peer-reviewed articles in the main astronomical journals. Your ability to access to the latter may be compromised if you are not at an institution with a subscription.
