Plato benchmark stars I. The initial benchmark sample
T. Merle, P. F. L. Maxted, O. L. Creevey +22
The ESA PLATO mission aims to detect and characterise Earth-size exoplanets orbiting bright, late-type stars using high-precision photometry and asteroseismology. Precise stellar p…
Gaia FGK Benchmark Stars: spectral library, metallicities and abundances of and Fe-peak elements of the third version
L. Casamiquela, C. Soubiran, P. Jofré +14
The accurate determination of chemical abundances in stars plays a pivotal role in understanding stellar structure and evolution, nucleosynthesis, and the chemical enrichment histo…
Host-star and exoplanet composition: Polluted white dwarf reveals depletion of moderately refractory elements in planetary material
Claudia Aguilera-Gómez, Laura K. Rogers, Amy Bonsor +6
Planets form from the same cloud of molecular gas and dust as their host stars. Confirming if planetary bodies acquire the same refractory element composition as their natal disc d…
Are Lithium-Rich Giants Binaries? A Radial Velocity Variability Analysis of 1,400 Giants
Matias Castro-Tapia, Claudia Aguilera-Gómez, Julio Chanamé
Low-mass giants with large amounts of lithium (Li) have challenged stellar evolution for decades. One of the possibilities usually discussed to explain them involves the interactio…
Evidence of extra-mixing in field giants as traced by lithium and carbon isotope ratio
Claudia Aguilera-Gómez, Matías I. Jones, Julio Chanamé
Although not predicted by standard stellar evolution, the surface abundance of light elements, such as lithium (Li), carbon, and nitrogen, changes during the red giant branch (RGB)…
Lithium abundance patterns of late-F stars: an in-depth analysis of the lithium desert
Claudia Aguilera-Gómez, Iván Ramírez, Julio Chanamé
We address the existence and origin of the lithium (Li) desert, a region in the Li - T_eff plane sparsely populated by stars. Here we analyze some of the explanations that have bee…
