An improved evolutionary model for stellar population applied to NGC 2903

Astrophysics and Space Science, 1990
We outline the revised physical assumption which have been incorporated into our previously published evolutionary model for stellar population synthesis in galaxies. Applying the present version of the model to well-defined zones on the nucleus and along a spiral arm of NGC 2903 we show that the star formation rate has increased during the lifetime of

Test of evolutionary models for stellar population studies

Journal of Astrophysics and Astronomy, 1994
Using the Andersen (1991) data on the mass, absolute visual magnitude, the effective surface temperature and the bolometric corrections, new calibrations for the mass vs. absolute visual magnitude and for the bolometric correction vs. effective surface temperature have been derived.

Evolutionary sequences of stellar models with semiconvection and convective overshoot. I. Z=0.008.

open access: yes, 1993
We present two grids of evolutionary stellar models covering the phases of core H- and He-burning for stars having masses in the range 0.6M. to 100M. with composition (Y = 0.25 and Z = 0.008). The computations were performed for two different mixing schemes in the convective regions, i.e.

Stellar Evolutionary Models: current uncertainties

AIP Conference Proceedings, 2009
In this last decade, our knowledge of evolutionary and structural properties of stars of different mass and chemical composition is significantly improved. This result has been achieved as a consequence of our improved capability in understanding and describing the physical behavior of stellar matter in the thermal regimes characteristic of the ...
