Solving the mystery of extreme light variability in the massive eccentric system MACHO 80.7443.1718
Piotr A. KoÅaczek-SzymaÅski, Piotr Åojko, 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…

Blue large-amplitude pulsators formed from the merger of low-mass white dwarfs
Piotr A. KoÅaczek-SzymaÅski, Andrzej Pigulski, Piotr Åojko
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…
