Measuring Be depletion in cool stars with exoplanets
Elisa Delgado Mena, Garik Israelian, Jonay I. González Hernández +2
We present new UVES spectra of a sample of 14 mostly cool unevolved stars with planetary companions with the aim of studying possible differences in Be abundance with respect to st…
Chemical Clues on the Formation of Planetary Systems: C/O vs Mg/Si for HARPS GTO Sample
Elisa Delgado Mena, Garik Israelian, Jonay I. González-Hernández +4
Theoretical studies suggest that C/O and Mg/Si are the most important elemental ratios in determining the mineralogy of terrestrial planets. The C/O ratio controls the distribution…
Light elements in stars with exoplanets
N. C. Santos, E. Delgado Mena, G. Israelian +7
It is well known that stars orbited by giant planets have higher abundances of heavy elements when compared with average field dwarfs. A number of studies have also addressed the p…
