Mass-Loss Return from Stars to Galaxies Workshop

Location: Pratt lecture hall (CfA)

Dates: May 20 and 21

We are planning a small informal workshop to discuss the topic of mass-loss return to galaxies and the resulting dust and metal enrichment process. The workshop will be 1.5 to 2 days and involve talks as well as lengthy discussion sessions in Pratt. The talks given will reflect the expertise of the participants. Talks will include measurements of mass-loss rates from a variety of evolved stars populations (e.g. Asymptotic Giant Branch stars, Red Giant stars, Planetary nebulae, Wolf-Rayet Stars, Luminous Blue Variables, Red Supergiants, O & B stars, Supernovae, Gamma Ray Bursts), metal enrichment measurements from abundance studies, theory of metal and dust enrichment in the evolution of galaxies, and measurement of dust(/metal) content of high-redshift submm galaxies. Your additional ideas & contributions are welcomed, please include them in the email for May 7. The talks given will reflect the expertise of the participants.
