PublicaciónA stellar stream remnant of a globular cluster below the metallicity floor
Stellar ejecta gradually enrich the gas out of which subsequent stars form, making the least chemically enriched stellar systems direct fossils of structures...

PublicaciónA test for asymptotic giant branch evolution theories: planetary nebulae in the Large Magellanic Cloud
We used a new generation of asymptotic giant branch (AGB) stellar models that include dust formation in the stellar winds to find the links between evolutionary...
