Post-Supernova Accretion of Light Elements onto a New-Born Neutron Star and NS 1987A
Natalia de Jesús Baz-Pérez, Dany Page, Simon Guichandut +3
We model early accretion of light elements, He, C, and O, onto a new-born neutron star using the public stellar evolution code MESA, simulating what may happen during the first few…
Weak Bursts on Slowly Accreting Neutron Stars
Sierra Casten, Simon Guichandut, Andrew Cumming +1
Nearly all observed thermonuclear X-ray bursts are thought to be triggered by the thermally unstable triple-alpha process. Unlike in accreting white dwarfs, the $\gtrsim10^{8} \mat…
Line detections in photospheric radius expansion bursts from 4U 1820-303
F. Barra, D. Barret, C. Pinto +3
Context: NICER (Neutron star Interior Composition ExploreR) is the instrument of choice for the spectral analysis of type I X-ray bursts, as it provides high throughput at X-ray CC…
The Challenges of Modeling Astrophysical Reacting Flows
Michael Zingale, Khanak Bhargava, Ryan Brady +5
Stellar evolution is driven by the changing composition of a star from nuclear reactions. At the late stages of evolution and during explosive events, the timescale can be short an…
