The spectroscopic indistinguishability of red giant branch and red clump stars
Thomas Masseron, Keith Hawkins
Stellar spectroscopy provides useful information on the physical properties of stars such as effective temperature, metallicity and surface gravity (log g). However, those photosph…
Gaia FGK Benchmark stars: Opening the black box of stellar element abundance determination
P. Jofre, U. Heiter, C. C. Worley +10
Gaia and its complementary spectroscopic surveys combined will yield the most comprehensive database of kinematic and chemical information of stars in the Milky Way. The Gaia FGK b…
Bright Metal-Poor Stars from the Hamburg/ESO Survey. II. A Chemodynamical Analysis
Timothy C. Beers, Vinicius M. Placco, Daniela Carollo +6
We obtain estimates of stellar atmospheric parameters for a previously published sample of 1777 relatively bright (9 < B < 14) metal-poor candidates from the Hamburg/ESO Survey. Th…
Chemical analysis of a carbon-enhanced very metal-poor star: CD-27 14351
Drisya Karinkuzhi, Aruna Goswami, Thomas Masseron
We present the first time abundance analysis of a very metal-poor carbon-enhanced star CD-27 14351 based on a high resolution (R ~ 48000) FEROS spectrum. Our abundance analysis per…
Nitrogen depletion in field red giants: mixing during the He flash?
T. Masseron, N. Lagarde, A. Miglio +2
We combine simultaneous constraints on stellar evolutionary status from asteroseismology, and on nitrogen abundances derived from large spectroscopic surveys, to follow nitrogen su…
How much can we trust high-resolution spectroscopic stellar chemical abundances?
S. Blanco-Cuaresma, T. Nordlander, U. Heiter +8
To study stellar populations, it is common to combine chemical abundances from different spectroscopic surveys/studies where different setups were used. These inhomogeneities can l…
