The evolution of supermassive Population III stars
Supermassive primordial stars forming in atomically-cooled halos at $z \sim15-20$ are currently thought to be the progenitors of the earliest quasars in the Universe. In this picture, the starExpand

Tidal interactions between binary stars drives lithium production in low-mass red giants
Theoretical models of stellar evolution predict that most of the lithium inside a star is destroyed as the star becomes a red giant. However, observations reveal that about 1% of red giants areExpand

CAN WE TRUST MODELS FOR ADIABATIC MASS LOSS
In interacting binaries, comparison of a donor star's radial response to mass loss (ML) with the response of its Roche radius determines whether ML persists and, if so, determines the timescale andExpand

He II recombination lines as a test of the nature of SN Ia progenitors in elliptical galaxies
To date, the question of which progenitor channel can reproduce the observed rate of Type Ia supernovae (SNe Ia) remains unresolved, with the single and double degenerate scenarios remaining theExpand

Upper limits on the luminosity of the progenitor of Type Ia supernova SN 2014J
We analysed archival data of Chandra pre-explosion observations of the position of SN2014J in M82. No X-ray source at this position was detected in the data, and we calculated upper limits on theExpand

Next generation population synthesis of accreting white dwarfs – I. Hybrid calculations using bse + mesa
Accreting, nuclear-burning white dwarfs (WDs) have been deemed to be candidate progenitors of Type Ia supernovae (SNe Ia), and to account for supersoft X-ray sources, novae, etc. depending on theirExpand

No hot and luminous progenitor for Tycho’s supernova
Type Ia supernovae have proven vital to our understanding of cosmology, both as standard candles and for their role in galactic chemical evolution; however, their origin remains uncertain. TheExpand

On the Maximum Mass of Accreting Primordial Supermassive Stars
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 timescales orExpand

Observatory science with eXTP
In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission for studies related to Observatory Science targets. These include flaring stars, supernovaExpand

On the Rotation of Supermassive Stars
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 their mass isExpand
