We have calculated synthetic spectra for HR 1099 for the wavelenffth region λ6425-6445 A, which includes the CaI λ6439 A and Fel λ6430 A lines, often used for the surface imaging of rapidly rotating late-type stars. The best agreement between the theoretical and observed spectra can be achieved with solar abundances in the both components of the system, except for Ca in the primary. Theoretical calculations give the possibility of estimating the influence of microturbulence, damping and blending on Ca I and Fe I line profiles. |
