Planet engulfment in the chemically anomalous HD 129171/HD 129209 pair

Anne Rathsam, Jorge Meléndez, Rodolfo Smiljanic +2

Binary systems composed of stars with similar parameters should have identical chemical composition. However, many chemically anomalous pairs have been found in the literature, suc…

A New Age-Activity Relation For Solar Analogs that Accounts for Metallicity

Gabriela Carvalho-Silva, Jorge Meléndez, Anne Rathsam +5

Determining stellar ages is challenging, particularly for cooler main-sequence stars. Magnetic evolution offers an observational alternative for age estimation via the age-chromosp…

Beryllium: The smoking gun of a rejuvenated star

Anne Rathsam, Jorge Meléndez, Amanda I. Karakas

Context. The chemistry and Galactic velocity components of the star HD 65907 suggest that despite its young isochronal age of 5 Gyr, it is in fact a merger of two old Populat…

The [Y/Mg] chemical clock in the Galactic Disk: The influence of metallicity and Galactic population in the solar neighbourhood

J. Shejeelammal, Jorge Meléndez, Anne Rathsam +1

Stellar ages are an important parameter to study the chemical evolution of the Galaxy. In recent years, several studies have established the existence of a relationship between che…

Lithium depletion in solar analogs: age and mass effects

Anne Rathsam, Jorge Meléndez, Gabriela Carvalho Silva

The main goal of this work is to evaluate the correlation between Li abundance, age, and mass. Using high-quality ESO/HARPS data (R 115 000; 270 SNR 1000), w…

Metallicity and age effects on lithium depletion in solar analogues

Giulia Martos, Jorge Meléndez, Anne Rathsam +1

The lithium present in the photospheres of solar-type stars is transported to the inner parts by convection, reaching regions even somewhat below the convection zone, by non-standa…
