CSFK CSI SZEMINÁRIUM / KONKOLY OBSERVATORY SEMINAR
Date: Mar 30, 2023 (Thursday) 16:00
Jamie Tayar (University of Florida):
Red Giant Chemistry: Interactions, Interiors, and Galactic Evolution
Red giants can be great tracers of galactic chemical evolution since they can
be studied to large distances. However, the mixture of elements they were
born with can be altered over the course of their lifetimes due to creation,
destruction, and mixing. In this talk, I will discuss the current state of
our ability to get precise ages for these stars using asteroseismology, and
how they can be used to map galactic chemical evolution. I will discuss
observed changes in surface chemistry that occur at the first dredge up and
above the red giant branch bump, and our current understanding of the
physical mechanisms for these changes. Finally, I will discuss some of the
impacts that binary interactions can have on these abundances and whether
they can be used as one tracer of current or past binary interactions.
The seminar will be held online via Zoom. You can join us via this link
