GTC Follow-up Observations of Very Metal-Poor Star Candidates from DESI
Carlos Allende Prieto, David S. Aguado, Jonay I. González Hernández +48
The observations from the Dark Energy Spectroscopic Instrument (DESI) will significantly increase the numbers of known extremely metal-poor stars by a factor of ~ 10, improving the…
The Pristine Inner Galaxy Survey (PIGS) VII: a discovery of the first inner Galaxy CEMP-r/s star
L. Mashonkina, A. Arentsen, D. S. Aguado +7
Well-studied very metal-poor (VMP, [Fe/H] < -2 ) stars in the inner Galaxy are few in number, and they are of special interest because they are expected to be among the oldest star…
The pristine nature of SMSS 16051443 revealed by ESPRESSO
D. S. Aguado, E. Caffau, P. Molaro +20
SMSS J160540.18144323.1 is the carbon-enhanced metal-poor (CEMP) star with the lowest iron abundance ever measured, [Fe/H]=-6.2, which was first reported with the SkyMapper tele…
Espresso observations of HE 01075240 and other CEMP-no stars with
D. Aguado, P. Molaro, E. Caffau +22
HE 01075240 is a hyper metal-poor star with . We performed high-res observations with the ESPRESSO spectrograph at the VLT to constrain the kinematical propert…
Information content of BP/RP spectra in Gaia DR3
Callum E. C. Witten, David S. Aguado, Jason L. Sanders +6
Gaia Data Release 3 has provided the astronomical community with the largest stellar spectroscopic survey to date ( 220 million sources). The low resolution (R50) blue pho…
Accurate Metallicities for Very Metal-Poor Stars from the Ca~II Infrared Triplet
Y. Osorio, D. S. Aguado, C. Allende-Prieto +2
The Ca~II H \& K lines are among the few features available to infer the metallicity of extremely metal-poor stars from medium-resolution spectroscopy. Unfortunately, these lines c…
