Abstract
Abundances of Fe, Si, Ni, Ti, Na, Mg, Cu, Zn, Mn, Cr and Ca in the atmosphere of the K-dwarf HD 77338 are
determined and discussed. HD 77338 hosts a hot Uranus-like planet and is currently the most metal-rich single star
to host any planet. Determination of abundances was carried out in the framework of a self-consistent approach
developed by Pavlenko et al. (2012). Abundances were computed iteratively by the ABEL8 code, and the process
converged after 4 iterations. We nd that most elements follow the iron abundance, however some of the iron peak
elements are found to be over-abundant in this star.
