We conclude that if stellar abundances with precisions of 0.01–0.03 dex could be reached in research of far more distant stars and stars on the enormous and supergiant branches, quite a few more exciting future purposes, of good relevance to stellar and galaxy evolution, are possible. Consequently, in planning abundance https://billionaire-brain-wave-re05925.post-blogs.com/53808159/the-basic-principles-of-the-stellar-abundance
