Surface distributions of Ti, Sr, Y, and Ba abundances reconstructed for 66 Eri A. The star is shown at five equidistant rotation phases at the inclination angle i = 75° and vertically oriented axis of rotation. The darker spots represent a higher concentration of chemical elements. The contours of equal abundance are plotted with a step of 0.1 dex for all chemical species. The thick line indicates the position of rotational equator, while the vertical bar shows rotational pole. The scale of the abundance maps is shown on the right. Abundances are given in a logarithmic scale relative to the Sun.
