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…
Grids of synthetic spectra for the GAIA mission
Tomaz Zwitter, Ulisse Munari, Fiorella Castelli
Two sets of grids of Kurucz ATLAS~9 model spectra are presented. The first one covers the GAIA spectral interval, while the second one which is still being computed covers the whol…
REM Optical Slitless Spectrograph (ROSS): an instrument for prompt low resolution spectroscopy of Gamma Ray Bursts
Eliana Palazzi, Elena Pian
Since the discovery of Gamma-Ray Bursts (GRBs), attempts have been made to detect correlated optical transient emission from these objects. In January 1999, the ROTSE I robotic tel…
Light and Heavy Elements in the Galactic Bulge
F. Matteucci, D. Romano, P. Molaro
The chemical evolution of the Galactic bulge is treated here in the context of an inside-out model for the Galaxy formation. We assume that this central region evolved even faster…
