The chemical composition of HIP34407/HIP34426 and other twin-star comoving pairs
I. Ramirez, S. Khanal, S. J. Lichon +4
We conducted a high-precision elemental abundance analysis of the twin-star comoving pair HIP34407/HIP34426. With mean error of 0.013 dex in the differential abundances (D[X/H]), a…
The Li-age correlation: the Sun is unusually Li deficient for its age
M. Carlos, J. Melendez, L. Spina +8
The present work aims to examine in detail the depletion of lithium in solar twins to better constrain stellar evolution models and investigate its possible connection with exoplan…
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.…
iota Horologii is unlikely to be an evaporated Hyades star
I. Ramirez, D. Yong, E. Gutierrez +3
We present a high-precision chemical analysis of iota Horologii, a planet-host field star thought to have formed in the Hyades. Elements with atomic number 6<=Z<=30 have abundances…
On the Iron Abundance Anomaly in K-dwarf and Hyades Stars
Patrick D. Aleo, Alexander C. Sobotka, Ivan Ramirez
Using standard 1D-LTE model atmosphere analysis, we provide an in-depth investigation of iron abundance as derived from neutral and singly ionization iron lines (Fe {\scriptsize{I,…
