The temporal evolution of neutron-capture elements in the Galactic discs
Lorenzo Spina, Jorge Meléndez, Amanda I. Karakas +8
Important insights into the formation and evolution of the Galactic disc(s) are contained in the chemical compositions of stars. We analysed high-resolution and high signal to nois…
Spectroscopic binaries in the Solar Twin Planet Search program: from substellar-mass to M dwarf companions
Leonardo A. dos Santos, Jorge Meléndez, Megan Bedell +6
Previous studies on the rotation of Sun-like stars revealed that the rotational rates of young stars converge towards a well-defined evolution that follows a power-law decay. It se…
High precision analysis of the solar twin HIP 100963
Jhon Yana Galarza, Jorge Meléndez, Ivan Ramírez +3
Methods. We used the HIRES spectrograph on the Keck I telescope to acquire high-resolution (R 70000) spectra with a high signal-to-noise ratio (S/N 400 - 650 pe…
Shallow extra mixing in solar twins inferred from Be abundances
M. Tucci Maia, J. Meléndez, M. Castro +5
Lithium and beryllium are destroyed at different temperatures in stellar interiors. As such, their relative abundances offer excellent probes of the nature and extent of mixing pro…
