The [Y/Mg] chemical clock and the stellar ages of solar-type stars in the solar neighbourhood
J. Shejeelammal, Jorge Meléndez, Anne Rathsam +1
Stellar ages are an important parameter for studying the chemical evolution of the Galaxy. To improve age estimates, various complementary methods to the conventional isochrone-fit…
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…
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…
Chemical evidence for planetary ingestion in a quarter of Sun-like stars
Lorenzo Spina, Parth Sharma, Jorge Meléndez +5
Stellar members of binary systems are formed from the same material, therefore they should be chemically identical. However, recent high-precision studies have unveiled chemical di…
