C3PO: Towards a complete census of co-moving pairs of stars. I. High precision stellar parameters for 250 stars
David Yong, Fan Liu, Yuan-Sen Ting +6
We conduct a line-by-line differential analysis of a sample of 125 co-moving pairs of stars (dwarfs and subgiants near solar metallicity). We obtain high precision stellar paramete…
Constraining Nucleosynthesis in Two CEMP Progenitors Using Fluorine
A. Mura-Guzmán, D. Yong, C. Abate +6
We present new fluorine abundance estimations in two carbon enhanced metal-poor (CEMP) stars, HE 1429-0551 and HE 1305+0007. HE 1429-0551 is also enriched in slow neutron-capture p…
Detailed chemical compositions of planet hosting stars: I. Exploration of possible planet signatures
F. Liu, D. Yong, M. Asplund +5
We present a line-by-line differential analysis of a sample of 16 planet hosting stars and 68 comparison stars using high resolution, high signal-to-noise ratio spectra gathered us…
Chemical abundances along the 1G sequence of the chromosome maps: The Globular Cluster NGC 3201
A. F. Marino, A. P. Milone, A. Sills +10
The Hubble Space Telescope (HST) UV Legacy Survey of Galactic Globular Clusters (GCs) has investigated multiple stellar populations by means of the "chromosome map" (ChM) diagnosti…
Chemical (in)homogeneity and atomic diffusion in the open cluster M67
F. Liu, M. Asplund, D. Yong +4
Context. The benchmark open cluster M67 is known to have solar metallicity and similar age as the Sun. It thus provides us a great opportunity to study the properties of solar twin…
An investigation of C, N and Na abundances in red giant stars of the Sculptor dwarf spheroidal galaxy
C. Salgado, G. S. Da Costa, J. E. Norris +1
The origin of the star-to-star abundance variations found for the light elements in Galactic globular clusters (GGCs) is not well understood, which is a significant problem for ste…
