안녕하십니까.

오는 수요일(9월 11일) 오후 4:00에 아래와 같이 2024년 하반기 정규 콜로키움이 진행될 예정입니다.

발표 후에는 연사와의 대화시간(5:00-5:40) 및 저녁 식사가 예정되어 있으니 많은 참여 부탁드립니다.

발표자: Prof. Timothy C Beers (University of Notre Dame)

제목: Identification of CEMP Stars in the Milky Way Based on Photometry

초록: 

I report on methods for the estimation of stellar parameters and elemental abundances, including [Fe/H], [C/Fe], and [Mg/Fe], for very large samples of stars in the disk and halo of the Milky Way, making use of a combination of narrow-band photometry from the J-PLUS and S-PLUS surveys and broad-band photometry from Gaia DR3.  The techniques employed can achieve estimates with precisions that are commensurate with that obtained from low- and medium-resolution spectroscopy.  I summarize the identification of on the order of 0.5 million carbon-enhanced metal-poor (CEMP) stars for future exploration of the chemo-dynamical properties of CEMP-no and CEMP-s stars in the halo and disk systems of the Galaxy.
