studies only constrained by observations of their global properties and external …

Metallicity and age effects on lithium depletion in solar analogues

G Martos, J Meléndez, A Rathsam… - Monthly Notices of the …, 2023 - academic.oup.com
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 …

The Li–age correlation: the Sun is unusually Li deficient for its age

M Carlos, J Meléndez, L Spina… - Monthly Notices of …, 2019 - academic.oup.com

Rotation Distributions around the Kraft Break with TESS and Kepler: The Influences of Age, Metallicity, and Binarity

EA Avallone, JN Tayar, JL van Saders… - The Astrophysical …, 2022 - iopscience.iop.org
Stellar rotation is a complex function of mass, metallicity, and age and can be altered by
binarity. To understand the importance of these parameters in main-sequence stars, we …

Lithium depletion and angular momentum transport in solar-type stars

Revisiting the 16 Cygni planet host at unprecedented precision and exploring automated tools for precise abundances

MT Maia, J Meléndez, D Lorenzo-Oliveira… - Astronomy & …, 2019 - aanda.org
The binary system 16 Cygni is key in studies of the planet-star chemical composition
connection, as only one of the stars is known to host a planet. This allows us to better assess …

Evidence of extra mixing in field giants as traced by the lithium and carbon isotope ratio

C Aguilera-Gómez, MI Jones, J Chanamé - Astronomy & Astrophysics, 2023 - aanda.org
