Something borrowed, something blue: The nature of blue metal-poor stars inferred from their colours and chemical abundances
C. J. Hansen, P. Jofre, A. Koch +2
Blue metal-poor stars (BMPs) are main sequence stars that appear bluer and more luminous than normal turnoff stars. They were originally singled out by using B-V and U-B colour cut…
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…
How much can we trust high-resolution spectroscopic stellar atmospheric parameters?
S. Blanco-Cuaresma, T. Nordlander, U. Heiter +8
The determination of atmospheric parameters depends on the use of radiative transfer codes (among other elements such as model atmospheres) to compute synthetic spectra and/or deri…
Stellar twins determine the distance of the Pleiades
Thomas Mädler, Paula Jofré, Gerard Gilmore +5
Since the release of the Hipparcos catalog in 1997, the distance to the Pleiades open cluster has been heavily debated. The distance obtained from Hipparcos and those by alternativ…
