Two unusual, radially pulsating stars

Radosław Smolec

We present the results of pulsation modelling of two unusual radially pulsating stars OGLE-BLG-T2CEP-279 and OGLE-BLG-RRLYR-02792. The former variable is the first BL Her-type star showing the period doubling effect. The second variable is a member of well-detached eclipsing binary system and the first member of a new class of variable stars that mimic RR Lyrae pulsation, but have unusually small masses.
