dc.description.abstract	A Binary Evolution Pulsator (BEP) is a low-mass (0.26Mꙩ ) member of a binary system, which pulsates as a result of a former mass transfer to its companion. The BEP mimics RR Lyrae-type pulsations, but has completely different internal structure and evolution history. Although there is only one known BEP (OGLE-BLG-RRLYR-02792), it has been estimated that approximately 0.2% of objects classified as RR Lyrae stars can be undetected Binary Evolution Pulsators. In the present work, this contamination value is re-evaluated using the population synthesis method. The output falls inside a range of values dependent on tuning the parameters in the StarTrack code, and varies from 0.06% to 0.43%	uk_UA
dc.description.sponsorship	It is a pleasure to thank G. Pietrzy«ski for substantive guidance to this project. I am gratefull to K. Belczynski for sharing the StarTrack code and for many useful and valuable instructions. This research is supported by the Polish National Science Centre grant PRELUDIUM 2012/07/N/ST9/04246.	uk_UA
