A blue-straggler merger scenario origin for the ~Persei binary system
D. Tarczay-Nehéz, L. Molnár, R. Z. Ãdám
We used \texttt{MIST} isochrone fitting and a dedicated grid of stellar evolution models computed with MESA to constrain the ages of the components of the Persei binary system…

Hidden massive eclipsing binaries in red supergiant systems: The hierarchical triple system KQ Puppis and other candidates
D. Jadlovský, L. Molnár, A. Ercolino +26
The majority of massive stars are part of binary systems that may interact during their evolution. However, not many RSGs are known binaries, and only a few have constrained orbita…
