Fundamental stellar parameters of benchmark stars from CHARA interferometry -- III. Giant and subgiant stars
I. Karovicova, T. R. White, T. Nordlander +3
Large spectroscopic surveys of the Milky Way need to be calibrated against a sample of benchmark stars to ensure the reliable determination of atmospheric parameters. We present ne…
Fundamental stellar parameters of benchmark stars from CHARA interferometry -- II. Dwarf stars
I. Karovicova, T. R. White, T. Nordlander +3
Stellar models applied to large stellar surveys of the Milky Way need to be properly tested against a sample of stars with highly reliable fundamental stellar parameters. We have e…
Two sequences in the age-metallicity relation as seen from [C/N] abundances in APOGEE
Paula Jofre
The age-metallicity relation is fundamental to study the formation and evolution of the disk. Observations have shown that this relation has a large scatter which can not be explai…
The consistency of chemical clocks among coeval stars
Francisca Espinoza-Rojas, Julio Chanamé, Paula Jofré +1
The abundance ratios of some chemical species have been found to correlate with stellar age, leading to the possibility of using stellar atmospheric abundances as stellar age indic…
Host-star and exoplanet compositions: a pilot study usinga wide binary with a polluted white dwarf
Amy Bonsor, Paula Jofre, Oliver Shorttle +3
Planets and stars ultimately form out of the collapse of the same cloud of gas. Whilst planets, and planetary bodies, readily loose volatiles, a common hypothesis is that they reta…
