Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. IV. Two bulge populations
Gravitational lensing: micro—Galaxy: bulge —Galaxy: formation —Galaxy: evolution —Stars: abundances
2011/10/20
Based on high-resolution (R~42000 to 48000) and high signal-to-noise (S/N~50 to 150) spectra obtained with UVES/VLT, we present detailed elemental abundances (O, Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Zn...
Cosmic Chemical Evolution with an Early Population of Intermediate Mass Stars
Cosmic Chemical Evolution Intermediate Mass Stars
2011/1/11
We explore the consequences of an early population of intermediate mass stars in the 2 - 8 M\odot range on cosmic chemical evolution. We discuss the implications of this population as it pertains to s...
