Workshop on "Lithium in the Cosmos", Paris, February 27 - 29
I participated in the workshop on "Lithium in the Cosmos" that was held in Paris between February 27 and 29, 2012, which was held to celebrate the 30th anniversary of the discovery of the Spite plateau. Accordingly, most of the workshop was focused on the cosmic lithium problem. The SOC accepted my proposition for a talk about "Lithium destruction and production observed in red giant stars", which mainly dealt with the results of our FLAMES survey for Li in bulge giants (see news item below), but also contained some new results. It was a very niceworkshop with lively discussion and exchange of ideas!
February 16, 2012: Article sumbitted to A&A!
On February 16, 2012, I submitted a new article to A&A. It is based on the same FLAMES-GIRAFFE spectra of the stars that were previously investigated for their Li content (see news item below). In this new article, we investigate abundances and kinematics of the stars, in order to characterise the Galactic bulge itself. With our sample, we confirm the presence of two populations of stars in the Galactic bulge! Watch out for this article on astro-ph, I hope it will appear there very soon!
Article accepted for A&A!
A new article has been accepted for publication at A&A on November 7, 2011! The article is titled "Lithium abundances along the red giant branch: FLAMES-GIRAFFE spectra of a large sample of low-mass bulge stars". Thomas Lebzelter and myself are the first authors (we both contributed equally to it, so we decided to make an alphabetical ordering among us). The paper describes the results of a spectroscopic survey of about 400 giant stars in the Galactic bulge to confine distinct episodes of Li-enrichment among low-mass K-type giants. Such distinct episodes of Li-enrichment were previously claimed from observations of K-type giants in the solar neighbourhood, we do however find evidence against these claims.Older news...
