Formation and Dynamical Evolution of Multiple Stellar Generations in Globular Clusters
Annibale D'Ercole, Enrico Vesperini, Francesca D'Antona +2
Some globular clusters are observed to host a population of second generation (SG) stars which show chemical anomalies and must have formed from gas containing matter processed in…
The effect of differential galactic winds on the chemical evolution of galaxies
S. Recchi, E. Spitoni, F. Matteucci +1
(Abridged) The aim of this paper is to study the basic equations of the chemical evolution of galaxies with gas flows. We focus on models in which the outflow is differential, name…
Galactic fountains and their connection with high and intermediate velocity clouds
E. Spitoni, S. Recchi, F. Matteucci
The aim of this paper is to calculate the expansion law and chemical enrichment of a supershell powered by the energetic feedback of a typical Galactic OB association at various ga…
The effect of clouds in a galactic wind on the evolution of gas-rich dwarf galaxies
S. Recchi, G. Hensler
(Abridged) We study the effects of interstellar clouds on the dynamical and chemical evolution of gas-rich dwarf galaxies. In particular, we focus on two model galaxies similar to…
Yields from AGB Stars and their Impact on the Chemical Evolution of Dwarf Galaxies
Simone Recchi
By means of 2--D chemodynamical simulations, we study the evolution of dwarf galaxies with structural parameters similar to IZw18 and to tidal dwarf galaxies. Different sets of yie…
Internal chemo-dynamical Modeling of Gas Exchange within Galaxies and with their Environment
Gerhard Hensler, Simone Recchi, Danica Kroeger +1
By a few but important examples as models of combined radiative and wind-driven HII regions and galactic winds we demonstrate the importance of refined small-to-medium scale studie…
The early evolution of tidal dwarf galaxies
S. Recchi, Ch. Theis, P. Kroupa +1
Context: Dwarf galaxies can arise from self-gravitating structures emerging from tidal tails. What fraction of the known dwarf galaxies in the Local Universe can have this origin i…
Star Formation Regulation, Gas cycles and the Chemical Evolution of Dwarf Irregular Galaxies
S. Recchi, G. Hensler
Due to their low gravitational energies, dwarf galaxies are greatly exposed to energetical influences from internal and external sources. By means of chemodynamical models we show…
Early evolution of Tidal Dwarf Galaxies
S. Recchi, P. Kroupa, Ch. Theis +1
Our aim is to study the evolution of tidal dwarf galaxies. The first step is to understand whether a model galaxy without Dark Matter can sustain the feedback of the ongoing star f…
A new formulation of the Type Ia SN rate and its consequences on galactic chemical evolution
F. Matteucci, N. Panagia, A. Pipino +3
In recent papers Mannucci et al. (2005, 2006) suggested, on the basis of observational arguments, that there is a bimodal distribution of delay times for the explosion of Type Ia S…
The refill of superbubble cavities
Simone Recchi, Gerhard Hensler
In this paper we study the late evolution of model galaxies after a single episode of star formation of different durations. The aim of the paper is to discover the timescale neede…
Dynamical and chemical evolution of NGC1569
S. Recchi, G. Hensler, L. Angeretti +1
Blue Compact Dwarf and Dwarf Irregular galaxies are generally believed to be unevolved objects, due to their blue colors, compact appearance and large gas fractions. Many of these…
Self-enrichment in globular clusters. I. An analytic approach
S. Recchi, I. J. Danziger
By means of analytical calculations, we explore the self-enrichment scenario for Globular Cluster formation. According to this scenario, an initial burst of star formation occurs i…
Continuous star formation in gas-rich dwarf galaxies
S. Recchi, G. Hensler
Blue Compact Dwarf and Dwarf Irregular galaxies are generally believed to be unevolved objects, due to their blue colors, compact appearance and large gas fractions. Many of these…
Continuous star formation in IZw18
S. Recchi, F. Matteucci, A. D'Ercole +1
We study the dynamical and chemical evolution of a galaxy similar to IZw18 under the assumption of a continuous star formation during bursts. We adopt a 2-D hydrocode coupled with…
Simulating the metal enrichment of the ICM
L. Tornatore, S. Borgani, F. Matteucci +2
We present results from Tree+SPH simulations of a galaxy cluster, aimed at studying the metal enrichment of the intra--cluster medium (ICM). The simulation code includes a fairly a…

We calculate the type Ia supernova rate for different star formation histories in galaxies by adopting the most popular and recent progenitor models. We show that the timescale for…

Effects of tidal interactions on the gas flows of elliptical galaxies
A. D'Ercole, S. Recchi, L. Ciotti
During a Hubble time, cluster galaxies may undergo several mutual encounters close enough to gravitationally perturb their hot, X-ray emitting gas flows. We ran several 2D, time de…
