Evolution of stars with 60 and 200 Msun: predictions for WNh stars in the Milky Way
Alex Camilo Gormaz-Matamala, Amedeo Romagnolo, Krzysztof Belczynski
We study in detail the evolution of two massive stars at solar metallicity (), by calculating their final masses, radial expansion, and chemical enrichment. We run evoluti…

The enigmatic origin of two dormant BH binaries: Gaia BH1 and Gaia BH2
Iwona Kotko, Sambaran Banerjee, Krzysztof Belczynski
The two systems, namely, Gaia~BH1 and Gaia~BH2, that have been confirmed as dormant (i.e., no X-ray emission detected) black hole (BH) - low-mass star binaries in the latest Gaia m…

Development of convective envelopes in massive stars: Implications for gravitational wave sources
Amedeo Romagnolo, Jakub Klencki, Alejandro Vigna-Gomez +1
The structure of stellar envelopes strongly influences the course and outcome of binary mass transfer, in particular of common envelope (CE) evolution. Convective envelopes can mos…
