Scientific paper

We discuss the unusual shape of Mrk 205 Fe Kα line in the light of microlensing influence of a caustic from the galaxy NGC 4319. The shape of the Fe Kα line may be described as disc emitted line deformed by microlensing effect of a star with mass less than 0.2 Msolar from the NGC 4319 star disc. In the paper we discuss the two scenarious of line variation, if the microlensing effect is present.
