[Astronomy seminar] Reminder: Astronomy departmental seminar Friday October 27 at 10:30am - Maryam Saberi (RoCS-UiO)

[Astronomy seminar announcements]

Dear all,

This is a reminder of the weekly SU astronomy departmental seminar that 
will take place in about 38 minutes, at 10:30am in room FC61 (AlbaNova 
building, 6th floor) and on zoom 
(https://stockholmuniversity.zoom.us/s/61002076352). As usual, we 
encourage you to attend in person if possible.

Title: Tracing the impact of Evolved Stars on the Galactic Chemical 
enrichment (ESGC)

Event: https://indico.fysik.su.se/e/maryam-saberi

Abstract:

In this presentation, I will discuss my ESGC project, which was recently 
awarded funding from the Research Council of Norway. The primary focus 
of my project is on evolved stars and their impact on enriching the 
chemical composition of interstellar mediums and galaxies. I will begin 
by providing an introduction to evolved stars and the chemistry active 
in their outflow. Solar-type stars eject a substantial amount of heavy 
elements and dust particles to the interstellar medium through strong 
stellar winds at late phases of stellar evolution, known as the 
asymptotic giant branch (AGB) phase, and therefore significantly 
influence the chemical composition of galaxies.

In ESGC project, I aim to target two main gaps in our knowledge that can 
be significantly advanced with current observational facilities, new 
laboratory molecular data, and upgraded chemical models. These gaps 
concern the role of AGB stars in the production of fluorine in our 
Galaxy, which is an essential element for the maintenance of solidity in 
our bones and teeth, and the impact of a chromospheric UV radiation 
field on the chemistry and dust-formation process around AGB stars. 
Through this project, I aim to create a more realistic picture of the 
recycled materials and stardust from evolved stars by considering the 
impact of internal UV radiation in the chemical models. Finally, I will 
outline the observational and simulation approaches I am planning to use 
to achieve the main objectives of the project and highlighting the 
unique opportunities associated with each approach.

We look forward to seeing many of you there. Thanks!
