  1. IL CONTENUTO STELLAREDELLE GALASSIE: BASI TEORICHE.Laura Greggio - OAPd Ciclo di lezioni sui fondamenti teorici alla base dei metodi interpretativi in uso per risalire alla storia di formazione stellare in galassie Lectures on Stellar Populations

  2. Carina: Dwarf Spheroidal Monelli et al. 2004 Lectures on Stellar Populations

  3. DISK FIELD BAR FIELD Recent enhancement (from 0.1 Gyr ago) Enhancement at 3.5 Gyr ago Old SF (from 10-3.0 Gyr ago) Large Magellanic Cloud Smecker-Hane et al. 2002 Lectures on Stellar Populations

  4. NGC 1705 – A Dwarf Blue Galaxy observations interpretation Annibali et al. 2003 Lectures on Stellar Populations

  5. Simulations: Color Coding Reflects AGE(Myr): <10Myr 10↔60 60↔1000 > 1000 SFR constant from 10 Myr to 2 Gyr ago SFR constant from now to 1 Gyr ago Lectures on Stellar Populations

  6. Integrated spectral indices to recover SFH in galaxies(from Thomas et al. 2005) Lectures on Stellar Populations

  7. Outline of the Course: • Summary of Stellar Evolution Review of general properties of stellar tracks, which determine the appearance of the HRD and its systematics. Close up on those features particularly relevant to decode SFH from the data. • Theoretical Tools for the Interpretation of the CMDs of Composite Stellar Populations in terms of SFH Going from the HRD to the CMD; check of the theoretical models. Relation between stellar counts in selected regions of the CMD and Mass of the stellar population. Simulations of CMDs. • Integrated Light of Stellar Populations Bolometric Magnitudes and contributions from different parts of the HRD; Magnitudes and Colors; Mass-to-Light ratios; Spectral Indices. Lectures on Stellar Populations
