The peculiar chemical pattern of the WASP-160 binary system: signatures of planetary formation and evolution?

Emiliano Jofré, Romina Petrucci, Yilen Gómez Maqueo Chew +8

Wide binary stars with similar components hosting planets provide a favorable opportunity for exploring the star-planet chemical connection. We perform a detailed characterization…

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…

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 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…

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…
