Gemini-GRACES high-quality spectra of Kepler evolved stars with transiting planets I. Detailed characterization of multi-planet systems Kepler-278 and Kepler-391
E. Jofré, J. M. Almenara, R. Petrucci +10
(abridged) Kepler-278 and Kepler-391 are two of the three evolved stars known to date on the RGB to host multiple short-period transiting planets. Moreover, these planets are among…
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…
Constraining the evolution of stellar rotation using solar twins
Diego Lorenzo-Oliveira, Jorge Meléndez, Jhon Yana Galarza +7
The stellar Rotation Age relation is commonly considered as a useful tool to derive reliable ages for Sun-like stars. However, in the light of \kepler\ data, the presence of…
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…
The temporal evolution of neutron-capture elements in the Galactic discs
Lorenzo Spina, Jorge Meléndez, Amanda I. Karakas +8
Important insights into the formation and evolution of the Galactic disc(s) are contained in the chemical compositions of stars. We analysed high-resolution and high signal to nois…
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…
