Contamination of RR Lyrae stars from Binary Evolution Pulsators
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...
