The Pristine survey -- XXIII. Data Release 1 and an all-sky metallicity catalogue based on Gaia DR3 BP/RP spectro-photometry
Nicolas F. Martin, Else Starkenburg, Zhen Yuan +38
We used the spectro-photometric information of ~219 million stars from Gaia's DR3 to calculate synthetic, narrow-band, metallicity-sensitive CaHK magnitudes that mimic the observat…
1D non-LTE corrections for chemical abundance analyses of very metal-poor stars
L. Mashonkina, Yu. Pakhomov, T. Sitnova +3
Detailed chemical abundances of very metal-poor (VMP, [Fe/H] < -2) stars are important for better understanding the First Stars, early star formation and chemical enrichment of gal…
Reanalysis of neutron-capture elements in the benchmark r-rich star CS 31082-001
H. Ernandes, M. J. Castro, B. Barbuy +4
We revisit the abundances of neutron-capture elements in the metal-poor ([Fe/H]=-2.9) r-process-rich halo star CS 31082-001. Partly motivated by the development of the new near-ult…
The Gaia-ESO Survey: homogenisation of stellar parameters and elemental abundances
A. Hourihane, P. Francois, C. C. Worley +59
The Gaia-ESO Survey is a public spectroscopic survey that has targeted stars covering all major components of the Milky Way from the end of 2011 to 2018, delivering i…
Automatic line selection for abundance determination in large stellar spectroscopic surveys
Georges Kordopatis, Vanessa Hill, Karin Lind
*Context: The optimisation of new multiplex spectrographs (resolution, wavelength range,...), their associated surveys (choice of setup), or their parameterisation pipelines requir…
