Stellar abundances from line statistics

Stellar abundances from line statistics

The method of linear statistical modeling has been combined with a rudimentary model of stellar photospheres to obtain abundance estimates for a large member of ''normal'' and peculiar, upper main sequence stars. The adopted standard abundances, obtained from published fine analy...

Zusammenfassung:The method of linear statistical modeling has been combined with a rudimentary model of stellar photospheres to obtain abundance estimates for a large member of ''normal'' and peculiar, upper main sequence stars. The adopted standard abundances, obtained from published fine analyses, can be fitted by our algorithms with about 0.5 dex as the standard deviation.
