Una galaxia irregular enana pillada en transición
Leo I es una de las galaxias enanas esferoidales más jóvenes del Grupo Local. Su relativo aislamiento, su historia de formación estelar (HFE) extendida y...
Uncovering fossils of the distant Milky Way with UNIONS: NGC 5466 and its stellar stream
We examine the spatial clustering of blue horizontal branch (BHB) stars from the u-band of the Canada-France Imaging Survey (CFIS, a component of the...
Uncovering the birth of the Milky Way through accurate stellar ages with Gaia
Accurate distances to individual Milky Way stars provided by Gaia have allowed us to derive stellar age distributions from colour─magnitude diagrams (CMD)...
Uncovering the birth of the Milky Way through accurate stellar ages with Gaia
Knowledge of the ages of the stars formed over a galaxy's lifetime is fundamental to an understanding of its formation and evolution. However, stellar ages are...
Understanding the evolution and dust formation of carbon stars in the Large Magellanic Cloud via the JWST
Context. Carbon stars have been, and still are, extensively studied. Given their complex internal structure and their peculiar chemical composition, they are...
The propagation of a shock wave into a medium is expected to heat the material beyond the shock, producing noticeable effects in intensity line ratios such as...
Unveiling the chemical fingerprint of phosphorus-rich stars. I. In the infrared region of APOGEE-2
Context The origin of phosphorus, one of the essential elements for life on Earth, is currently unknown. Prevalent models of Galactic chemical evolution (GCE)...
Unveiling the chemical fingerprint of phosphorus-rich stars: II. Heavy-element abundances from UVES/VLT spectra
Context. The atmospheres of phosphorus-rich (P-rich) stars have been shown to contain between 10 and 100 times more P than our Sun. Given its crucial role as an...
Unveiling the purely young star formation history of the SMC's northeastern shell from colour-magnitude diagram fitting
We obtain a quantitative star formation history (SFH) of a shell-like structure ('shell') located in the northeastern part of the Small Magellanic Cloud (SMC)...
