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…
Hydrodynamical simulations of proton ingestion flashes in Type I X-ray Bursts
Simon Guichandut, Michael Zingale, Andrew Cumming
We perform the first multidimensional fluid simulations of thermonuclear helium ignition underneath a hydrogen-rich shell. This situation is relevant to Type I X-ray bursts on neut…
The imprint of convection on Type I X-ray bursts: Pauses in photospheric radius expansion lightcurves
Simon Guichandut, Andrew Cumming
Motivated by the recent observation by NICER of a type I X-ray burst from SAX J1808.4-3658 with a distinct "pause" feature during its rise (Bult et al. 2019), we show that bursts w…
Expanded atmospheres and winds in Type I X-ray bursts from accreting neutron stars
Simon Guichandut, Andrew Cumming, Maurizio Falanga +2
We calculate steady-state models of radiation-driven super-Eddington winds and static expanded envelopes of neutron stars caused by high luminosities in type I X-ray bursts. We use…
