Diffusion of Lithium and Beryllium in Evolving, Nonrotating Main-Sequence A and F Stars

摘要: The evolution of the internal distribution lithium and beryllium in envelopes nonrotating Population I A F stars is computed for whole main-sequence lifetime stars. calculations include effects changing envelope structure due to core helium gravitational settling, convective mixing, nuclear burning, diffusion presence radiative forces dragging by main gas constituents. new OPAL opacities are used. Since adjustable parameters were calibrated using Sun, presented here entirely from first principles
