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…
