The effects of individual metal contents on isochrones for C, N, O, Na, Mg, Al, Si, and Fe
(IOP Publishing, 2016-07-28)The individual characteristics of C, N, O, Na, Mg, Al, Si, and Fe on isochrones have been investigated in this study. Stellar models have been constructed for various mixtures in which the content of each element is changed ... -
From the color-magnitude diagram of omega centauri and (super-) asymptotic giant branch stellar models to a galactic plane passage gas purging chemical evolution scenario
(IOP Publishing, 2012-10-01)We have investigated the color-magnitude diagram of omega Centauri and find that the blue main sequence (bMS) can be reproduced only by models that have a helium abundance in the range Y = 0.35-0.40. To explain the faint ... -
Photometric properties of stellar populations in Galactic globular clusters: the role of the Mg-Al anticorrelation
(EDP Sciences S A, 2013-06)We have computed low-mass stellar models and synthetic spectra for an initial chemical composition that includes the full C-N, O-Na, and Mg-Al abundance anticorrelations observed in second-generation stars belonging to a ...
