A quasi-star is born: formation and evolution of accreting quasi-stars as a pathway to Little Red Dots at non-zero metallicity
J. Roman-Garza, D. Schaerer, C. Charbonnel +5
The recently discovered Little Red Dots identified by the James Webb Space Telescope are compact high-redshift sources whose properties have motivated models involving black holes…
Massive stellar cannibals: How stellar mergers drive mass-loss in extremely massive stars
J. Roman-Garza, T. Fragos, C. Charbonnel +3
It has been theorized that the formation of extremely massive and supermassive stars () could plausibly be the outcome of stellar mergers in low metallicity (…
Globular cluster formation from inertial inflows: accreting extremely massive stars as the origin of abundance anomalies
Mark Gieles, Paolo Padoan, Corinne Charbonnel +2
We use the inertial-inflow model of massive star formation to describe the formation of globular clusters (GCs) in turbulent molecular clouds. A key aspect of this model is that th…
Collision-induced mass loss and mass gain on an extremely massive star. An analytical approach and a static proto-globular cluster test-case
Laura RamÃrez-Galeano, Corinne Charbonnel, Tassos Fragos +3
The objective of this study is to analytically explore mass loss and gain induced by stellar collisions on a gas-accreting extremely massive star (aEMS, 10^3 <= M/M_sun <= 10^4). W…
