Solving the mystery of extreme light variability in the massive eccentric system MACHO 80.7443.1718
Piotr A. Kołaczek-Szymański, Piotr Łojko, Andrzej Pigulski +2
The evolution of massive stars is heavily influenced by their binarity, and the massive eccentric binary system MACHO 80.7443.1718 (ExtEV) serves as a prime example. This study exp…
BRITE nascent binaries
Andrzej Pigulski
Nascent binaries (NBs) are binary systems with very low mass ratios, less than ~0.2, in which the more massive component is an O- or B-type main-sequence star, while the secondary…
OGLE-BLAP-001 and ZGP-BLAP-08: two possible magnetic blue large-amplitude pulsators
Andrzej Pigulski, Piotr A. Kołaczek-Szymański, Marta Święch +2
Blue large-amplitude pulsators (BLAPs) are a newly discovered group of compact pulsating stars whose origin needs to be explained. Of the existing evolutionary scenarios that could…
Blue large-amplitude pulsators formed from the merger of low-mass white dwarfs
Piotr A. Kołaczek-Szymański, Andrzej Pigulski, Piotr Łojko
Blue large-amplitude pulsators (BLAPs) are a recently discovered group of hot stars pulsating in radial modes. Their origin needs to be explained, and several scenarios for their f…
Exploring extreme brightness variations in blue supergiant MACHO 80.7443.1718: Evidence for companion-driven enhanced mass loss
Piotr Antoni Kołaczek-Szymański, Piotr Łojko, Andrzej Pigulski +2
Evolution of massive stars is dominated by interactions within binary systems. Therefore, it is necessary to investigate all forms of interaction in binary systems that may affect…
BRITE-Constellation photometry of $\bpi^5$ Orionis, an ellipsoidal SPB variable
M. Jerzykiewicz, A. Pigulski, G. Handler +5
Results of an analysis of the BRITE-Constellation photometry of the SB1 system and ellipsoidal variable Ori (B2\,III) are presented. In addition to the orbital light-variatio…
