Chemical Evolution of Late-type Dwarf Galaxies - The windy starburst dwarfs NGC 1569 and NGC 1705
Donatella Romano, Monica Tosi, Francesca Matteucci
Thanks to the capabilities of modern telescopes and instrumentation, it is now possible to resolve single stars in external dwarf galaxies, provided they are bright enough. For gal…
Initial mass function and galactic chemical evolution models
Donatella Romano, Cristina Chiappini, Francesca Matteucci +1
In this contribution we focus on results from chemical evolution models for the solar neighbourhood obtained by varying the IMF. Results for galaxies of different morphological typ…
Quantifying the uncertainties of chemical evolution studies. I. The stellar initial mass function and the stellar lifetimes
Donatella Romano, Cristina Chiappini, Francesca Matteucci +1
The stellar initial mass function and the stellar lifetimes are basic ingredients of chemical evolution models, for which different recipes can be found in the literature. In this…
Chemical abundances in quasar host galaxies and environments from narrow absorption line systems
Valentina D'Odorico, Stefano Cristiani, Donatella Romano +2
We determined C, N and alpha-element relative abundances in the gas surrounding six QSOs at an average redshift of < z > ~ 2.4, by studying six narrow associated absorption systems…
