Grids of stellar models with rotation: V. Models from 1.7 to 120 Msun at zero metallicity
Laura J. Murphy, Jose H. Groh, Sylvia Ekstrom +10
Understanding the nature of the first stars is key to understanding the early universe. With new facilities such as JWST we may soon have the first observations of the earliest ste…
On the ALMA observability of nascent massive multiple systems formed by gravitational instability
D. M. -A. Meyer, A. Kreplin, S. Kraus +3
Massive young stellar object (MYSOs) form during the collapse of high-mass pre-stellar cores, where infalling molecular material is accreted through a centrifugally-balanced accret…
Stellar models and isochrones from low-mass to massive stars including pre-main sequence phase with accretion
L. Haemmerlé, P. Eggenberger, S. Ekström +6
Grids of stellar models are useful tools to derive the properties of stellar clusters, in particular young clusters hosting massive stars, and to provide information on the star fo…
On the episodic excursions of massive protostars in the Hertzsprung-Russell diagram
D. M. A. Meyer, L. Haemmerlé, E. I. Vorobyov
Massive protostars grow and evolve under the effect of rapid accretion of circumstellar gas and dust, falling at high rates (-).…
Formation of massive black holes via collisions and accretion
D. R. G. Schleicher, M. A. Fellhauer, T. Boekholt +13
To explain the observed population of supermassive black holes at z~7, very massive seed black holes or, alternatively, super-Eddington scenarios are needed to reach final masses o…
The magnetic fields of intermediate-mass T Tauri stars : I. Magnetic detections and fundamental stellar parameters
Florent Villebrun, Evelyne Alecian, Gaitee Hussain +13
Context. The origin of the fossil magnetic fields detected in 5 to 10% of intermediate-mass main sequence stars is still highly debated. Aims. We want to bring observational constr…
Titans of the Early Universe: The Prato Statement on the Origin of the First Supermassive Black Holes
Tyrone E. Woods, Bhaskar Agarwal, Volker Bromm +30
In recent years, the discovery of massive quasars at z~7 has provided a striking challenge to our understanding of the origin and growth of supermassive black holes in the early Un…
On the Rotation of Supermassive Stars
Lionel Haemmerlé, Tyrone E. Woods, Ralf S. Klessen +2
Supermassive stars born from pristine gas in atomically-cooled haloes are thought to be the progenitors of supermassive black holes at high redshifts. However, the way they accrete…
Magnetic fields of intermediate mass T Tauri stars
A. Lavail, O. Kochukhov, G. A. J. Hussain +3
Aims. In this paper, we aim to measure the strength of the surface magnetic fields for a sample of five intermediate mass T Tauri stars and one low mass T Tauri star from late-F to…
On the Maximum Mass of Accreting Primordial Supermassive Stars
T. E. Woods, Alexander Heger, Daniel J. Whalen +2
Supermassive primordial stars are suspected to be the progenitors of the most massive quasars at z~6. Previous studies of such stars were either unable to resolve hydrodynamical ti…
Grids of stellar models with rotation - III. Models from 0.8 to 120 Msun at a metallicity Z = 0.002
Cyril Georgy, Sylvia Ekström, Patrick Eggenberger +11
(shortened) We provide a grid of single star models covering a mass range from 0.8 to 120 Msun with an initial metallicity Z = 0.002 with and without rotation. We discuss the impac…
The past and future evolution of a star like Betelgeuse
Georges Meynet, Lionel Haemmerle, Sylvia Ekstrom +3
We discuss the physics and the evolution of a typical massive star passing through an evolutionary stage similar to that of Betelgeuse. After a brief introduction recalling various…
