Description

The identification of lines of radioactive elements (Tc, Pm and elements with 83<Z<100) in the spectra of chemically peculiar stars HD101065, HR465, HD965 is made. Three possible explanations are proposed: natural radioactive decay of Th and U in the upper levels of stellar atmospheres, contamination of stellar atmosphere by recent SN explosion, and spallation reactions
