  • Yields of low and intermediate mass stars

    We present a set of low and intermediate mass star yields based on a modeling of the TP-AGB phase which affects the production of nitrogen and carbon. These yields are evaluated...
  • Stellar models grids. Z=0.02, M=0.8 to 125

    We present new stellar models based on updated physics (opacities, expanded nuclear network and mass loss rates). We compute stellar models suitable for the mean solar...
  • BVIJHK properties of Single Stellar Populations

    We describe a large grid of photometric properties of single stellar populations that focuses on the near infrared properties of intermediate age populations. The underlying...
  • Automatic observation rendering (AMORE)

    A new method, AMORE (AutoMatic Observation REnderer) - based on a genetic algorithm optimizer, is presented for the automated study of colour-magnitude diagrams. The method...
  • Spectrophotometry of simulated Stellar Populations

    A new set of evolutionary synthesis spectra are presented for Simple Stellar Populations (SSPs) covering ranges in metallicity from 0.02<=Z/Z_{sun}<=2.5 and ages from...
  • Radial oscillations of relativistic stars

    We present a new survey of the radial oscillation modes of neutron stars. This study complements and corrects earlier studies of radial oscillations. We present an extensive...
  • Evolution models for {alpha}-enhanced stars

    We present four large sets of evolutionary tracks for stars with initial chemical compositions [Y=0.250, Z=0.008], [Y=0.2773, Z=0.019], [Y=0.320, Z=0.040] and [Y=0.390, Z=0.070]...
  • Line-strength predictions in Elliptical Galaxies

    This table shows the line-strength predictions computed for: CaT, NaI, and MgI in the near infrared and Mgb, Mg2, Fe52, Fe53, NaD and H{beta}, in the blue-visible range, for...
  • Dust formation in WC stars

    The following table gives the ratefile of the chemical model. Columns {alpha}, {beta} and {gamma} give the rate k at temperature T in the Arrhenius form: k = {alpha} *...
  • Star formation in early-type galaxies

    We analyze the star formation properties of a sample of 21 shell galaxies and 30 early-type galaxies members of interacting pairs, located in low density environments (Longhetti...
  • Chemical spiral galaxies models

    We have extended our chemical and cosmological galaxy evolution model to calculate the abundance evolution for altogether 16 different elements in spiral galaxies in a...
  • PSR J1012+5307 evolutionary tracks

    We present a set of evolutionary tracks for white dwarfs with helium cores in the mass range from 0.179 to 0.414M_{sun}. The tracks are based on a 1M{sun}_ model sequence...
  • Low-mass stars evolutionary models

    Physical properties and absolute magnitudes of low-mass stars for different initial metallicity [M/H], helium mass fraction Y and mixing length parameter Lmix: mass (in solar...
  • Evolution models of elliptical galaxies. III.

    In this study we present a simple model of elliptical galaxies aimed at interpreting the gradients in colours and narrow band indices observed across these systems. Salient...
  • Structure and evolution of low-mass stars

    Properties of Very Low mass stars for different initial metallicity [M/H] and Helium mass fraction: mass (in solar mass), age (in Gyrs) effective temperature (in K), log of...
  • Star cluster evolution

    A model of spectral evolution of star forming galaxies of various metallicity has been used to study the relation between the optical emission line ratio...
  • Evolution models of elliptical galaxies. II.

    In this paper we present new chemo-spectro-photometric models of elliptical galaxies in which infall of primordial gas is allowed to occur. They aim to simulate the collapse of...
  • Rotating neutron stars models. I.

    (no description available)
  • Star formation in galaxies

    Evolutionary models of disk galaxies are presented (table3), and are confronted with a sample of late type galaxies from the Tully (Nearby Galaxies, see Cat. ) and the de...
