Please join us for a talk on Dying Stars & The Enrichment of Galaxies with Greg Sloan, Sr. Research Associate, Infrared Spectrograph Science Center, Cornell University

A fundamental problem in astronomy is understanding how stars
die and in the process enrich their environment with dust and
the products of fusion reactions from their cores.  We have
tackled this question using infrared spectra from the Spitzer
Space Telescope of samples of stars in globular clusters and
nearby dwarf galaxies in the Local Group.  These samples
segregate the stars by initial mass and elemental abundances,
so that we can quantify the impact of both on the mass-loss
and dust-formation processes.  We are also preparing for the
next generation of space and ground-based telescopes by
monitoring populations of stars in different environments
photometrically, which will lead to better spectroscopic
samples in future studies.
