[Astronomy seminar] Reminder: Astronomy departmental seminar Friday December 1 at 10:30am - Heitor Ernandes (Lund University)

[Astronomy seminar announcements]

Dear all,

This is a reminder of the weekly SU astronomy departmental seminar that 
will take place in about 33 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: The Bright Future of Ground-Based Near-UV Spectroscopy for R-rich 
Stars
Event: https://indico.fysik.su.se/e/heitor-ernandes

Abstract:
Stars that present an enhancement in r-process elements are rare objects 
in the sky. Only 72 stars are categorised as r-II stars, which show a 
high level of enhancement in the elements such as Europium. They are the 
key to understanding the astrophysical site where these heavy elements 
can be synthesised and the time scale of these events. However, to have 
a complete picture of these r-process creation sites, we need the 
complete abundance pattern for chemically peculiar stars such as 
actinide boost and CEMP stars. To access all this information, it is 
needed to observe under 4000 Å. However, this region is heavily affected 
by atmosphere absorption. Overcoming this challenge, the forthcoming 
generation of instruments, exemplified by VLT-CUBES, holds significant 
promise for refining near-UV observational capabilities from the ground.
