The properties of supermassive stars in galaxy merger driven direct collapse I: models without rotation
Lionel Haemmerlé
The formation of the most massive quasars observed at high redshifts requires extreme accretion rates ( M yr). Inflows of M yr are found…
Magnetic fields limit the mass of Population III stars even before the onset of protostellar radiation feedback
Piyush Sharda, Shyam H. Menon, Roman Gerasimov +5
The masses of Population III stars are largely unconstrained since no simulations exist that take all relevant primordial star formation physics into account. We perform the first…
General-relativistic instability in rapidly accreting supermassive stars in the presence of dark matter
Lionel Haemmerlé
The collapse of supermassive stars (SMSs) via the general-relativistic (GR) instability would provide a natural explanation to the existence of the most extreme quasars. The presen…
Direct collapse of exceptionally heavy black holes in the merger-driven scenario
Lorenz Zwick, Lucio Mayer, Lionel Haemmerlé +1
We revisit the conditions present in supermassive discs (SMDs) formed by the merger of gas-rich, metal-enriched galaxies at red-shift . We find that SMDs naturally form h…
Backtracing the internal rotation history of the Cep star HD 129929
Sébastien Salmon, Facundo Moyano, Patrick Eggenberger +2
HD 129929 is a slowly-rotating Cephei pulsator with a rich spectrum of detected oscillations, including two rotational multiplets. The asteroseismic interpretation revealed the…
Very massive star winds as sources of the short-lived radioactive isotope Al
S. Martinet, G. Meynet, D. Nandal +7
The Al short-lived radioactive nuclide is the source of the observed galactic diffuse -ray emission at 1.8 MeV. While different sources of Al have been explored, s…
Trapping of HII regions in Population III star formation
Ondrej Jaura, Simon C. O. Glover, Katharina M. J. Wollenberg +3
Radiative feedback from massive Population III (Pop III) stars in the form of ionising and photodissociating photons is widely believed to play a central role in shutting off accre…
Grids of stellar models with rotation VI: Models from 0.8 to 120 at a metallicity Z = 0.006
Patrick Eggenberger, Sylvia Ekström, Cyril Georgy +14
Context: Grids of stellar models, computed with the same physical ingredients, allow one to study the impact of a given physics on a broad range of initial conditions and are a key…
Star-planet interactions. V. Dynamical and equilibrium tides in convective zones
Suvrat Rao, Georges Meynet, Patrick Eggenberger +5
When planets are formed from the protoplanetary disk and after the disk has dissipated, the evolution of their orbits is governed by tidal interactions, friction, and gravitational…
Massive star formation by accretion I. Disc accretion
Lionel Haemmerlé, Patrick Eggenberger, Georges Meynet +2
Massive stars likely form by accretion and the evolutionary track of an accreting forming star corresponds to what is called the birthline in the HR diagram. The shape of this birt…
