  • EVOLUZIONE STELLARE TEORICA

  • DA UN PUNTO DI VISTA QUALITATIVO, LO SCENARIO INTERPRETATIVO EBEN DEFINITO DA MOLTI ANNI. TUTTAVIA, MOLTE ED IMPORTANTI PROBLEMATICHENECESSITANO ANCORA UNA ACCURATA INDAGINE QUANTITATIVA

  • LEVOLUZIONE STELLARE TEORICA COME STRUMENTO DI INDAGINE

  • Le collaborazioni scientifichenazionali

  • Le collaborazioni scientificheinternazionaliEuropean Southern Observatory (Germania)Max Planck Institute for Astrophysics (Monaco)Max Planck Institute for Extraterrestrial Physics (Monaco)John Moores University Liverpool (UK)Space Telescope Science Institute (Baltimora)Cerro Tololo Inter-American Observatory NOAO (Cile)Imperial College, Blackett Laboratory (Londra)Institut dEstudis Espacials de Catalunya (Barcellona)Universitat politcnica de Catalunya (Barcellona)University of Victoria (Canada)Warsaw University Observatory (Polonia)University of Illinois (USA)Universidad Catolica (Santiago, Cile)Universidad de Granada (Spagna)Instituto de Astrofisica de Canarias (Spagna)University of Texas Austin (USA)Caltech Pasadena (USA)Observatoire de Nice (Francia)

  • Alcuni risultatiEvoluzione stellare come test della fisica

    Strutture stellari di massa molto piccola

    Evoluzione stellare come tool per studiare lUniverso

    Levoluzione chimica della materia (AGB, Stelle massive)

    Progenitori di Supernovae

    Sintesi di popolazione

  • La teoria dellevoluzione stellare: gli ingredientiLe equazioni delle strutture stellari

    Gli inputs fisici:Equazione di StatoOpacitSezioni durto nucleariI meccanismi microscopici:Diffusione atomicaLevitazione radiativaI meccanismi macroscopici:Convezione superadiabaticaOvershootingPulsi convettivi

  • LelioseismologiaLanalisi dello spettro pulsazionale solare ed il confronto con vari modelli solari standardconsente di testare laccuratezza delle varie assunzioni riguardo alla fisica in gioco nelle stelle di piccola massa
