Stellar Evolutionary Models: challenges from observations of stellar systems [PDF]
Proceedings of the International Astronomical Union, 2006 Abstract We briefly review some constraints for stellar models in various mass regimes and evolutionary stages as provided by observational data from spectroscopy to multi-wavelenghts photometry. The accuracy of present generation of stellar models can be significantly improved only through an extensive comparison between theory and observations.

Evolutionary sequences of stellar models with new radiative opacities. III. Z=0.0004 and Z=0.05
, 1994 We present detailed tabulations of two large grids of stellar models with the extreme initial chemical composition [Z=0.0004, Y=0.230], and [Z=0.050, Y=0.352]. The models are computed with the most recent radiative opacities (OPAL) by Iglesias et al.

Young Populous Clusters in the Magellanic Clouds – Implications for Stellar Evolutionary Models [PDF]
Symposium - International Astronomical Union, 1999 We present new UV, visual and Hα photometry obtained with the WFPC2 of NGC 330, NGC 1818, NGC 2004 and NGC 2100, four young populous clusters in the MCs. We present observational evidence for a degree of convective core overshoot in excess of that currently applied in standard models.

Evolutionary sequences of stellar models with new radiative opacities. IV. Z=0.004 and Z=0.008
, 1994 We present detailed tabulations of two large grids of stellar models with the initial chemical compositions [Y=0.240, Z=0.004] and [Y=0.250, Z=0.008], computed with the most recent radiative opacities (OPAL) by Iglesias et al. (1992). This paper continues the series initiated by Bressan et al.

Multiple Stellar Populations: the evolutionary framework [PDF]
, 2015 In these last years a huge amount of both spectroscopical and photometric data has provided a plain evidence of the fact that Galactic globular clusters (GCs) host various stellar sub-populations characterized by peculiar chemical patterns.

The Astronomical Journal, 2022 Abstract Population III stars were the first stars to form after the Big Bang and are believed to have made the earliest contribution to the metal content of the universe beyond the products of the Big Bang nucleosynthesis. These stars are theorized to have had extremely short life spans and therefore would only be observable at high ...

YONSEI EVOLUTIONARY POPULATION SYNTHESIS (YEPS) MODEL. I. SPECTROSCOPIC EVOLUTION OF SIMPLE STELLAR POPULATIONS [PDF]
The Astrophysical Journal Supplement Series, 2012 We present a series of papers on the year-2012 version of Yonsei Evolutionary Population Synthesis (YEPS) model which is constructed on over 20 years of heritage. This first paper delineates the spectroscopic aspect of integrated light from stellar populations older than 1 Gyr.

Magnetic Inflation and Stellar Mass. IV. Four Low-mass Kepler Eclipsing Binaries Consistent with Non-magnetic Stellar Evolutionary Models [PDF]
The Astronomical Journal, 2019 Abstract Low-mass eclipsing binaries (EBs) show systematically larger radii than model predictions for their mass, metallicity, and age. Prominent explanations for the inflation involve enhanced magnetic fields generated by rapid rotation of the star that inhibit convection and/or suppress flux from the star via starspots.
