Isotopic Composition of Zr in S-Stars
Abstract
It is shown that ZrO bands profiles in the S-star HR 1105 can be interpreted in the view at the presence of some Zr in the atmosphere which appears to be the product of heavy elements decay. The best explanation of absorption bands is obtained assuming, that 60% of Zr has isotopic composition corresponding to the s-process and 40% of the isotopic composition of heavy elements of decay spectra.
