  • Pre-main sequence evolutionary tracks

    Magnetic fields are at the heart of the observed stellar activity in late-type stars, and they are presumably generated by a dynamo mechanism at the interface layer (tachocline)...
  • Evolution of massive AGB stars. III.

    We present the first simulations of the full evolution of super-AGB stars through the entire thermally pulsing AGB phase. We analyse their structural and evolutionary properties...
  • UV properties of starbursts

    We have computed evolutionary synthesis models covering metallicities from PopIII to solar, a wide range of IMFs, and two star-formation histories (bursts and constant...
  • Overproduction factors of s-nuclei in massive stars

    Using the "post-processing" technique, we explore the role of the convective overshooting on the production of s-nuclei in stellar models of different initial mass and...
  • Rotating massive MS stars evolutionary models

    We present a dense grid of evolutionary tracks and isochrones of rotating massive main-sequence stars. We provide three grids with different initial compositions tailored to...
  • Evolutionary tracks to estimate DLA depletions

    Silicates are an important component of interstellar dust that has been poorly investigated in high redshift galaxies. As a preliminary step to studying silicates at high...
  • Pisa pre-main sequence tracks and isochrones

    In recent years new observations of pre-main sequence stars (pre-MS) with Z=0.008, we also provided models with two different initial deuterium abundances. The characteristics...
  • Synthetic spectra of galactic globular clusters

    We calculated synthetic spectra for typical chemical element mixtures (i.e., a standard alpha-enhanced distribution, and distributions displaying CN and ONa anticorrelations)...
  • Stellar models with rotation. 0.8<M<120, Z=0.014

    Many topical astrophysical research areas, such as the properties of planet host stars, the nature of the progenitors of different types of supernovae and gamma ray bursts, and...
  • Evolutionary tracks for pre-main sequence stars

    The apsidal-motion constants k_j_ and the moment of inertia are often used to study the apsidal-motion and tidal evolution of double-lined eclipsing binaries and planetary...
  • Basic tracks at Zinit=0.006

    We present dense grids of stellar models suitable for comparison with observable quantities measured with great precision, such as those derived from binary systems or...
  • Grid of stellar models, asteroseismology

    The availability of asteroseismic constraints for a large sample of stars from the missions CoRoT and Kepler paves the way for various statistical studies of the seismic...
  • WDA and WDB apsidal-motion constants

    The internal structure constants k_j_ and the radius of gyration are useful tools for investigating the apsidal motion and tidal evolution of close binaries and planetary...
  • Chemistry of IRC+10216 inner wind modelled

    We model the chemistry of the inner wind of the carbon star IRC+10216 and consider the effects of periodic shocks induced by the stellar pulsation on the gas to follow the...
  • Outer boundary conditions for evolving cool WD

    White dwarf evolution is essentially a gravothermal cooling process, which, for cool white dwarfs, depends on the treatment of the outer boundary conditions. We provide detailed...
  • D-burning in core accretion objects

    Our aim is to study deuterium burning in objects forming according to the core accretion scenario in the hot and cold start assumption and what minimum deuterium burning mass...
  • White dwarf cooling sequences

    We present new diagnostics of white dwarf (WD) cooling sequences and luminosity functions (LFs) in the near-infrared (NIR) bands that will exploit the sensitivity and resolution...
  • Models for rotating stars

    B-type stars are known to rotate at various velocities, including very fast rotators near the critical velocity as the Be stars. In this paper, we provide stellar models...
  • Evolution and CNO yields of Z=10^-5^ stars

    Our main goals are to get a deeper insight into the evolution and final fates of intermediate-mass, extremely metal-poor (EMP) stars. We also aim to investigate the C, N, and O...
  • Mass and age of extreme low-mass white dwarfs

    The number of detected extremely low mass (ELM) white dwarf stars has increased drastically in recent year thanks to the results of many surveys. In addition, some of these...
