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…
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…
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 Solar Twin Planet Search: The age - chromospheric activity relation
Diego Lorenzo-Oliveira, Fabrício C. Freitas, Jorge Meléndez +8
It is well known that the magnetic activity of solar type stars decreases with age, but it is widely debated in the literature whether there is a smooth decline or if there is an e…
Lithium abundance patterns of late-F stars: an in-depth analysis of the lithium desert
Claudia Aguilera-Gómez, Iván Ramírez, Julio Chanamé
We address the existence and origin of the lithium (Li) desert, a region in the Li - T_eff plane sparsely populated by stars. Here we analyze some of the explanations that have bee…
