Spectroscopic study on the beryllium abundances of red giant stars
@article{Takeda2014SpectroscopicSO, title={Spectroscopic study on the beryllium abundances of red giant stars}, author={Yoichi Takeda and Akito Tajitsu}, journal={Publications of the Astronomical Society of Japan}, year={2014}, volume={66}, pages={91} }
An extensive spectroscopic study was carried out for the beryllium abundances of 200 red giants (mostly of late G and early K type), which were determined from the near-UV Be II 3131.066 line based on high-dispersion spectra obtained by Subaru/HDS, with an aim of investigating the nature of surface Be contents in these evolved giants; e.g., dependence upon stellar parameters, degree of peculiarity along with its origin and build-up timing. We found that Be is considerably deficient (to widely…
