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 survey -- XX: GTC follow-up observations of extremely metal-poor stars identified from Pristine and LAMOST
Anke Arentsen, David S. Aguado, Federico Sestito +5
Ultra metal-poor stars ([Fe/H] < -4.0) are very rare, and finding them is a challenging task. Both narrow-band photometry and low-resolution spectroscopy have been useful tools for…
The Pristine Inner Galaxy Survey (PIGS) VI: Different vertical distributions between two DIBs at 442.8 nm and 862.1 nm
He Zhao, Mathias Schultheis, Anke Arentsen +8
Although diffuse interstellar bands (DIBs) were discovered over 100 years ago, for most of them, their origins are still unknown. Investigation on the correlations between differen…
The Pristine Inner Galaxy Survey (PIGS) V: a chemo-dynamical investigation of the early assembly of the Milky Way with the most metal-poor stars in the bulge
Federico Sestito, Kim A. Venn, Anke Arentsen +13
The investigation of the metal-poor tail in the Galactic bulge provides unique information on the early Milky Way assembly and evolution. A chemo-dynamical analysis of 17 very meta…
Antaeus: a retrograde group of tidal debris in the Milky Way's disk plane
Pierre-Antoine Oria, Wassim Tenachi, Rodrigo Ibata +5
We present the discovery of a wide retrograde moving group in the disk plane of the Milky Way using action-angle coordinates derived from the \textit{Gaia} DR3 catalog. The structu…
Mining S-PLUS for Metal-Poor Stars in the Milky Way
Vinicius M. Placco, Felipe Almeida-Fernandes, Anke Arentsen +4
This work presents the medium-resolution () spectroscopic follow-up of 522 low-metallicity star candidates from the Southern Photometric Local Universe Survey (S-PLUS…
