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…
The chemical abundance pattern of the extremely metal-poor thin disk star 2MASS J1808-5104 and its origins
Mohammad K. Mardini, Anna Frebel, Rana Ezzeddine +6
We present a high-resolution (), high signal-to-noise () Magellan/MIKE spectrum of the bright extremely metal-poor star 2MASS~J18085104. We find [Fe/H] = $…
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…
