Chemical abundances of 1111 FGK stars from the HARPS-GTO planet search sample. III. Sulfur
Ana Rita Costa Silva, Elisa Delgado Mena, Maria Tsantaki
Context. Elemental abundances are of prime importance to help us reconstruct the origin and evolution of stars and galaxies in our Universe. Sulfur abundances have not been as heav…
TESS Asteroseismology of the known red-giant host stars HD 212771 and HD 203949
Tiago L. Campante, Enrico Corsaro, Mikkel N. Lund +45
The Transiting Exoplanet Survey Satellite (TESS) is performing a near all-sky survey for planets that transit bright stars. In addition, its excellent photometric precision enables…
The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition
The MSE Science Team, Carine Babusiaux, Maria Bergemann +258
(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unvei…
Abundance to age ratios in the HARPS-GTO sample with Gaia DR2: Chemical clocks for a range of [Fe/H]
E. Delgado Mena, A. Moya, V. Adibekyan +8
[ABRIDGED] The purpose of this work is to evaluate how several elements produced by different nucleosynthesis processes behave with stellar age and provide empirical relations to d…
The Metallicity-Period-Mass Diagram of low-mass exoplanets
S. G. Sousa, V. Adibekyan, N. C. Santos +14
The number of exoplanet detections continues to grow following the development of better instruments and missions. Key steps for the understanding of these worlds comes from their…
On the iron ionization balance of cool stars
M. Tsantaki, N. C. Santos, S. G. Sousa +3
High-resolution spectroscopic studies of solar-type stars have revealed higher iron abundances derived from singly ionized species compared to neutral, violating the ionization equ…
