Abstract
I will present an overview of our present understanding of the late-stage evolution of intermediate-mass stars (approximately 1 to 8 times the mass of our Sun). Both single stars and those in binary systems will be examined. I will pay particular attention to the post-red giant phase(s) of evolution, when most of a star's mass is ejected into the ambient interstellar medium. The physical and chemical characteristics of the "planetary nebulae" that are formed at this point in a star's life provide insights into the many processes governing both stellar death and Galactic enrichment. I will conclude this talk by outlining current and future research questions in this field of astrophysics.
Coffee and tea will be served 20 minutes prior to the seminar.
Anyone interested is welcome to attend.
