Models for the interpretation of CaT and the blue Spectral Indices in Elliptical Nuclei
M. Molla, M. L. Garcia-Vargas
We present a grid of theoretical models where the calculation of absorption line spectral indices in both the blue and red wavelength ranges is done with the same evolutionary synt…
Metals and dust content across the galaxies M101 and NGC 628
J. M. Vilchez, M. Relano, R. Kennicutt +3
We present a spatially resolved study of the relation between dust and metallicity in the nearby spiral galaxies M101 (NGC 5457) and NGC 628 (M74). We explore the relation between…
PopStar I: Evolutionary synthesis models description
M. Molla, M. L. Garcia-Vargas, A. Bressan
We present new evolutionary synthesis models for Simple Stellar Populations for a wide range of ages and metallicities. The models are based on the Padova isochrones. The core of t…
Constraining the evolutionary histories of spiral disks
M. Molla, E. Hardy
We study the old problem of the uniqueness of chemical evolution models. We showed in Molla et al. (1999) that multiphase models for three Virgo cluster galaxies were able to repro…
Some caveats about the evolution of the N/O abundance and the star formation history
M. Molla, M. Gavilan
We carefully analyze how the abundance of Nitrogen over Oxygen evolves when dependent on metallicity stellar yields with a primary component of N proceeding from AGBs stars are use…
Bulges
M. Molla, F. Ferrini, G. Gozzi
We model the evolution of the galactic bulge and of the bulges of a selected sample of external spiral galaxies, via the multiphase multizone evolution model. We address a few ques…
