The local stellar population

European Journal of Physics, 2003
We describe an undergraduate experiment that can be used to place the Sun in context with the properties of our nearest stellar neighbours. Using stars selected on the basis of their trigonometric parallaxes and spreadsheet software, the Hertzsprung–Russell diagram and luminosity function are constructed for stars within 16 pc, showing that the Sun is ...

Stellar Evolution and Stellar Populations in Galaxies

1992
Models of population synthesis are resting on an ensemble of other models, data and assumptions, in particular the models of stellar evolution, the data on initial compositions, the data on stellar spectra, the initial mass function (IMF), the star formation rate (SFR), the infall rate, etc… Here we shall concentrate on the properties of stellar models

Summary on stellar populations

Proceedings of the International Astronomical Union, 2005
ELTs will bring galaxies within 5 Mpc or more “as close as the Magellanic Clouds”. This is why stellar populations is such an exciting subject for ELTs. We can resolve galaxies into stars and learn their history (1) from the “fossil record” of old stars and (2) looking back in time. The confrontation of these two views will bring important new insights

Stellar Populations and Mergers

1990
Our Galaxy has four stellar populations: the disk, the thick disk, the bulge, and the halo. Did they form out of a single proto-Galactic nebula, with each population being but a different stage in the process? Or have at least some of them nothing to do with the origins and evolution of the others, as expected from mergers?

Stellar Evolution and Populations

2017
The theory of star formation and evolution is one of the most successful Astrophysical theories in last century. Based on this theory, people can predict the fate of a single star and various physical properties of a stellar population. Lots of conclusions of stellar populations in star clusters are based on the star formation and evolution theory ...
