From Giant Envelopes to Rapidly Contracting Cores in Rotating Population III Stars from to
Devesh Nandal, John Chisholm, Daniel J. Whalen +4
Population III (Pop III) stars link the chemical enrichment of the early Universe to the formation of the first massive black holes, yet their evolution remains poorly understood a…
Habitable Zones Around Massive Stars: From the Main Sequence to Supergiants
Devesh Nandal, Abraham Loeb
Massive stars dominate the feedback of young stellar populations, yet their ultraviolet fields and winds are often presumed to preclude Earth like habitability. We test this by map…
Dark-Matter-Powered Population III Evolution: Lifetimes, Rotation, and Quasi-Homogeneity in massive Stars
Anais Pauchet, Devesh Nandal
Population III stars supplied the first light and metals in the Universe, setting the pace of re-ionisation and early chemical enrichment. In dense haloes their evolution can be st…
Growth of Metal-Enriched Supermassive Stars by Accretion and Collisions
Devesh Nandal, Sunmyon Chon
Supermassive stars (SMSs) are candidate progenitors of massive black hole seeds and may contribute to anomalous abundance patterns in high-redshift galaxies and globular clusters.…
The evolution of protostars powered by dark matter annihilation. I. Fiducial model and first results
Devesh Nandal, Konstantinos Topalakis, Jonathan C. Tan +4
The existence of billion-solar-mass quasars at redshifts poses a formidable challenge to theories of black hole formation, requiring pathways for the rapid growth of…
The Future of Solar modelling: requirements for a new generation of solar models
Gael Buldgen, Gloria. Canocchi, Arthur. Le Saux +22
Helioseismology and solar modelling have enjoyed a golden era thanks to decades-long surveys from ground-based networks such as for example GONG, BiSON, IRIS and the SOHO and SDO s…
Rotating Supermassive Pop III Stars On The Main Sequence
Devesh Nandal, Gaël Buldgen, Daniel J. Whalen +3
The detection of billion-solar-mass supermassive black holes (SMBHs) within the first billion years of cosmic history challenges conventional theories of black hole formation and g…
Constraints on the properties of macroscopic transport in the Sun from combined lithium and beryllium depletion
G. Buldgen, A. Noels, A. M. Amarsi +5
Context. The Sun is a privileged laboratory of stellar evolution, thanks to the quality and complementary nature of available constraints. Using these observations, we are able to…
Grids of stellar models with rotation VIII: Models from 1.7 to 500 at metallicity
Yves Sibony, Kendall G. Shepherd, Norhasliza Yusof +12
Grids of stellar evolution models with rotation using the Geneva stellar evolution code (Genec) have been published for a wide range of metallicities. We introduce the last remaini…
The Evolution of Accreting Population III Stars at 10-10 M/yr
Devesh Nandal, Lorenz Zwick, Daniel J. Whalen +3
The first stars formed over five orders of magnitude in mass by accretion in primordial dark matter halos. We study the evolution of massive, very massive and supermassive primordi…
Rapidly rotating Population III stellar models as a source of primary nitrogen
Sophie Tsiatsiou, Yves Sibony, Devesh Nandal +12
The first stars might have been fast rotators. This would have important consequences for their radiative, mechanical and chemical feedback. We discuss the impact of fast initial r…
Impact of different approaches for computing rotating stellar models I. The solar metallicity case
Devesh Nandal, Georges Meynet, Sylvia Ekström +6
The physics of stellar rotation plays a crucial role in the evolution of stars, their final fate and the properties of compact remnants. Diverse approaches have been adopted to inc…
The evolution and impact of 3000 M stars in the early Universe
D. Nandal, E. Farrell, G. Buldgen +2
We present evolutionary models of massive, accreting population III stars with constant and variable accretion rates until the end of silicon burning, with final masses of 1000 - 3…
Critical accretion rates for rapidly growing massive Population III stars
Devesh Nandal, John A. Regan, Tyrone E. Woods +3
Efforts to understand the origin and growth of massive black holes observed in the early Universe have spurred a strong interest in the evolution and fate of rapidly-accreting prim…
The evolutionary stage of Betelgeuse inferred from its pulsation periods
Hideyuki Saio, Devesh Nandal, Georges Meynet +1
Betelgeuse is a well known bright red supergiant that shows semi-regular variations with four approximate periods of 2200, 420, 230, and 185 days. While the longest period was cust…
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…
