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 Pop III.1 Protostars Powered by Dark Matter Annihilation. II. Dependence on WIMP Properties
Konstantinos Topalakis, Devesh Nandal, Jonathan C. Tan
The rapid appearance of supermassive black holes (SMBHs) at requires efficient pathways to form massive black hole seeds. We investigate whether annihilation of weakly…
Supermassive Stars Match the Spectral Signatures of JWST's Little Red Dots
Devesh Nandal, Abraham Loeb
The James Webb Space Telescope (JWST) has unveiled a population of enigmatic, compact sources at high redshift known as ``Little Red Dots'' (LRDs), whose physical nature remains a…
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…
1000-10,000 M Primordial Stars Created the Nitrogen Excess in GS 3073 at
Devesh Nandal, Daniel J. Whalen, Muhammad A. Latif +1
The advent of the James Webb Space Telescope has revealed a wealth of new galaxies just a few hundred Myr after the Big Bang. Some of these galaxies exhibit unusual N/O ratios that…
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…
Planet Formation at Cosmic Dawn: Planetesimals in HO-Rich Disks Around Low-Mass Stars
Eduard I. Vorobyov, Daniel J. Whalen, Muhammad A. Latif +5
Primordial, or Pop III, supernovae (SNe) were the first, great nucleosynthetic engines in the Universe, forging the heavy elements required for the later formation of planets, and…
