The Evolution Of Carbon, Sulphur, and Titanium Isotopes from High-Redshift to the Local Universe
G. L. Hughes, B. K. Gibson, L. Carigi +3
Recent observations of carbon, sulphur, and titanium isotopes at redshifts z~1 and in the local stellar disc and halo have opened a new window into the study of isotopic abundance…
The delayed contribution of low and intermediate mass stars to chemical galactic enrichment: An analytical approach
I. Franco, L. Carigi
We find a new analytical solution for the chemical evolution equations, taking into account the delayed contribution of all low and intermediate mass stars (LIMS) as one representa…
The Helium and Heavy Elements Enrichment of the Galactic Disk
Leticia Carigi, Manuel Peimbert
We present chemical evolution models for the Galactic disk. We also present a new determination of X, Y, and Z for M17 a Galactic metal-rich Hii region. We compare our models for t…
On the Primordial Helium Abundance and the DeltaY/DeltaO Ratio
M. Peimbert, V. Luridiana, A. Peimbert +1
We present a review on the determination of the primordial helium abundance, Yp, based on the study of hydrogen and helium recombination lines in extragalactic H II regions. We als…
Models of the Solar Vicinity: The Metal Rich Stage
L. Carigi
I present a review of chemical evolution models of the solar neighborhood. I give special attention to the necessary ingredients to reproduce the observed [Xi/Fe] ratios in nearby…
Chemical Evolution of the Galactic Bulge
Brad K. Gibson, Angela J. MacDonald, Patricia Sanchez-Blazquez +1
Adopting a single-zone framework, with accretion of primordial gas on a free-fall timescale, the chemical evolution of the Galactic bulge is calculated, assuming (i) a correspondin…
