Seminar: Molybdenum in the Galactic disk and bulge

Different elements form in different ways, and studying their abundance in stars can provide clues to which environments they form in. Additionally, they can tell us something about the chemical history of our galaxy. One set of elements are the very heavy ones, that form through neutron-capture processes, providing another set of time-scales and insights, compared to commonly used alpha- and iron-peak elements.

In my talk, I’ll introduce both the neutron-capture processes, and present my latest research within this field of Galactic Archaeology, where I have determined the abundance of the element molybdenum (Mo) in red giants in the Milky Way disk and bulge, in order to make a differential comparison of the two stellar populations and gain a larger understanding for the chemical composition of the bulge. Additionally, the nucleosynthetic origin of Mo is a complex and fascinating one, which I hope to bring more light to.

We will also take a closer look at a chemically peculiar star in the bulge that emerged from the data. Hope to see many of you there!

We shall leave for lunch at around 12:15. There will be fika after the seminar.
