Chemical evolution models: the role of type Ia supernovae in the -elements over Iron relative abundances and their variations in time and space
O. Cavichia, M. Mollá, J. J. Bazán +6
The role of type Ia supernovae (SN Ia), mainly the Delay Time Distributions (DTDs) determined by the binary systems, and the yields of elements created by different explosion mecha…

Revising the cross correlation technique at high spectral resolution
S. Zamora, A. I. Díaz
Cross-correlation techniques have been used since 1974 for measuring velocity shifts and velocity dispersions from stellar and nebular spectra and, since 1979, the analysis based o…

Galactic Chemical Evolution
M. Mollá, O. Cavichia, R. da Costa +2
We analyze the evolution of oxygen abundance radial gradients resulting from our chemical evolution models calculated with different prescriptions for the star formation rate (SFR)…
