abstract:
The newly discovered group of compact pulsating stars known as blue large-amplitude pulsators (BLAPs) pose a challenge to the theory of evolution. Several theories were proposed to explain the scenarios of their formation. All they assume that the progenitors of BLAPs were or still are the members of binary systems. To understand the evolution of BLAPs, the most accurate characterisation of this group of pulsating stars is needed. We present the results of our analysis of the Zwicky Transient Facility (ZTF) project photometric data for known and candidate BLAPs, focusing on the detection of their binarity.
