TP-AGB stars with envelope burning
P. Marigo, A. Bressan, C. Chiosi
In this paper we focus on the TP-AGB evolution of intermediate-mass stars experiencing envelope burning (M=4-5Mo). The approach we have adopted is a semi-analytical one as it combi…
To what Extent are Mg2 and <Fe> indicators of Mg and Fe Abundances?
R. Tantalo, A. Bressan, C. Chiosi
The gradients in line strength indices such as Mg2 and <Fe> (Carollo & Danziger 1994a,b; Carollo et al. 1993), and their increase toward massive system (Worthey et al. 1992, Faber…
Ages and Metallicities in Elliptical Galaxies from the H_beta, <Fe>, and Mg2 Diagnostics
R. Tantalo, C. Chiosi, A. Bressan
Systematic variations in the line strength indices H_beta, Mg2, and <Fe> are observed across elliptical galaxies and from one object to another. Furthermore arguments are given for…
Source Counts and Background Radiation
A. Franceschini, H. Aussel, A. Bressan +7
Our present understanding of the extragalactic source counts and background radiation at infrared and sub-mm wavelengths is reviewed. Available count data are used to constrain evo…
Models of Galaxy Evolution from the UV to the Sub-Millimeter
Gian Luigi Granato, Laura Silva, Lugi Danese +3
We present the first results of a detailed modeling of chemical and photometric evolution of galaxies including the effects of a dusty interstellar medium. A chemical evolution cod…
Old Massive Ellipticals and S0 in the Hubble Deep Field Vanish from View at : Possible Solutions of the Enigma
Alberto Franceschini, Laura Silva, Gian Luigi Granato +2
We have investigated the properties of a bright K-band selected sample of early-type galaxies in the Hubble Deep Field, as representative of the field galaxy population. This datas…
