Probing the Przybylski star for Deuterium
arXiv:2302.02487 · doi:10.1002/asna.20220133
Abstract
The Przybylski star spectrum has been studied in order to search for deuterium lines. Since this star is extremely enriched in the s-process elements, which are the product of interaction between free neutrons and seed nuclei, we might as well expect to detect deuterium in this star. However, no visible spectroscopic manifestation of deuterium has been detected. Perhaps, the reason of this result is the convective "destruction" of this isotope.
