Evolution of wide O star binaries through their LBV stage. Population synthesis with mass-ejection-driven orbital evolution
Xiao-Tian Xu, Philipp Podsiadlowski, Norbert Langer +6
Context. Long-period Wolf-Rayet (WR) star binaries produced by mass transfer are predicted to be abundant, but are observationally rare. This yields constraints on the evolution of…
A solution to the tension of burning on neutron stars and nuclear physics
Y. Cavecchi, D. Galloway, A. Heger +8
When neutron stars accrete matter from a companion star, this matter forms a disc around them and eventually falls on their surface. Here, the fuel can ignite into bright flashes c…
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…
The Impact of Initial Composition on Massive Star Evolution and Nucleosynthesis
Christopher West, Alexander Heger, Benoit Cote +2
We study the sensitivity of presupernova evolution and supernova nucleosynthesis yields of massive stars to variations of the initial composition. We use the solar abundances from…
Partial tidal disruption events: The elixir of life
Megha Sharma, Daniel J. Price, Alexander Heger
In our Galactic Center, about 10,000 to 100,000 stars are estimated to have survived tidal disruption events, resulting in partially disrupted remnants. These events occur when a s…
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…
