An ancient system hidden in the Galactic plane?
Federico Sestito, Emma Fernandez-Alvar, Rebecca Brooks +19
We analyse high signal-to-noise ESPaDOnS/CFHT spectra of 20 very metal-poor stars (VMP; [Fe/H]~) in the solar neighbourhood (within kpc), selected to be on planar or…
The accreted Galaxy: An overview of TESS metal-poor accreted stars candidates
Danielle de Brito Silva, Paula Jofré, Clare Worley +2
The Milky Way is a mosaic of stars from different origins. In particular, metal-poor accreted star candidates offer a unique opportunity to better understand the accretion history…
The Pristine Inner Galaxy Survey (PIGS) IX. The largest detailed chemical analysis of very metal-poor stars in the Sagittarius dwarf galaxy
Federico Sestito, Sara Vitali, Paula Jofre +16
The most metal-poor stars provide valuable insights into the early chemical enrichment history of a system, carrying the chemical imprints of the first generations of supernovae. T…
Early emission lines in SN 2024ggi revealed by high-resolution spectroscopy
Thallis Pessi, Régis Cartier, Emilio Hueichapan +6
We present an analysis of very early high-resolution spectroscopic observations of the Type II supernova (SN) 2024ggi, a nearby SN that occurred in the galaxy NGC 3621 at a distanc…
On the evolutionary history of a simulated disc galaxy as seen by phylogenetic trees
Danielle de Brito Silva, Paula Jofré, Patricia B. Tissera +12
Phylogenetic methods have long been used in biology, and more recently have been extended to other fields - for example, linguistics and technology - to study evolutionary historie…
Gaia FGK Benchmark Stars: fundamental Teff and log g of the third version
Caroline Soubiran, Orlagh Creevey, Nadege Lagarde +8
Context. Large spectroscopic surveys devoted to the study of the Milky Way, including Gaia, use automated pipelines to massively determine the atmospheric parameters of millions of…
Unraveling UBC 274: a morphological, kinematical and chemical analysis of a disrupting open cluster
L. Casamiquela, J. Olivares, Y. Tarricq +8
We do a morphological, kinematic and chemical analysis of the disrupting cluster UBC 274 (2.5 Gyr, pc) to study its global properties. We use HDBSCAN to obtain a new membe…
The detailed chemical abundance patterns of accreted halo stars from the optical to infrared
Andreia Carrillo, Keith Hawkins, Paula Jofré +3
Understanding the assembly of our Galaxy requires us to also characterize the systems that helped build it. In this work, we accomplish this by exploring the chemistry of accreted…
J-PLUS: Detecting and studying extragalactic globular clusters -- the case of NGC 1023
Danielle de Brito Silva, Paula Coelho, Arianna Cortesi +19
Extragalactic globular clusters (GCs) are key objects for studying the history of galaxies. The arrival of wide-field surveys such as the Javalambre Photometric Local Universe Surv…
