Modelling the solar twin 18 Sco

M. Bazot, O. Creevey, J. Christensen-Dalsgaard +1

Solar twins are objects of great interest in that they allow us to understand better how stellar evolution and structure are affected by variations of the stellar mass, age and che…

The R-Process Alliance: Chemical Abundances for a Trio of R-Process-Enhanced Stars -- One Strong, One Moderate, One Mild

Madelyn Cain, Anna Frebel, Maude Gull +9

We present detailed chemical abundances of three new bright (V ~ 11), extremely metal-poor ([Fe/H] ~ -3.0), r-process-enhanced halo red giants based on high-resolution, high-S/N Ma…

Revisiting the science case for near-UV spectroscopy with the VLT

C. J. Evans, B. Barbuy, B. Castilho +8

In the era of Extremely Large Telescopes, the current generation of 8-10m facilities are likely to remain competitive at far-blue visible wavelengths for the foreseeable future. Hi…

A formation timescale of the Galactic halo from Mg isotopes in dwarf stars

Marilia Carlos, Amanda I. Karakas, Judith G. Cohen +2

We determine magnesium isotopic abundances of metal poor dwarf stars from the galactic halo, to shed light on the onset of asymptotic giant branch (AGB) star nucleossynthesis in th…

Detailed chemical compositions of the wide binary HD 80606/80607: revised stellar properties and constraints on planet formation

F. Liu, D. Yong, M. Asplund +5

Differences in the elemental abundances of planet hosting stars in binary systems can give important clues and constraints about planet formation and evolution. In this study we pe…

The Chemical Homogeneity of Sun-like Stars in the Solar Neighborhood

Megan Bedell, Jacob L. Bean, Jorge Melendez +9

The compositions of stars are a critical diagnostic tool for many topics in astronomy such as the evolution of our Galaxy, the formation of planets, and the uniqueness of the Sun.…
