Evolution of fission-ignited supernova properties with uranium enrichment
Alex Deibel, C. J. Horowitz, M. E. Caplan
Type-Ia supernovae (SN Ia) are powerful stellar explosions that provide important distance indicators in cosmology. There is significant tension between values of the Hubble consta…
Modeling the Galactic Neutron Star Population for Use in Continuous Gravitational Wave Searches
Brendan T. Reed, Alex Deibel, C. J. Horowitz
Searches for continuous gravitational waves from \textit{unknown} Galactic neutron stars provide limits on the shapes of neutron stars. A rotating neutron star will produce gravita…
Nuclear Physics of the Outer Layers of Accreting Neutron Stars
Zach Meisel, Alex Deibel, Laurens Keek +2
Now 50 years since the existence of the neutron star crust was proposed, we review the current understanding of the nuclear physics of the outer layers of accreting neutron stars.…
Nuclear Reactions in the Crusts of Accreting Neutron Stars
R. Lau, M. Beard, S. S. Gupta +13
X-ray observations of transiently accreting neutron stars during quiescence provide information about the structure of neutron star crusts and the properties of dense matter. Inter…
Different accretion heating of the neutron star crust during multiple outbursts in MAXI J0556-332
A. S. Parikh, J. Homan, R. Wijnands +11
The transient neutron star (NS) low-mass X-ray binary MAXI J0556332 provides a rare opportunity to study NS crust heating and subsequent cooling for multiple outbursts of the sa…
Deep crustal heating by neutrinos from the surface of accreting neutron stars
F. J. Fattoyev, Edward F. Brown, Andrew Cumming +4
We present a new mechanism for deep crustal heating in accreting neutron stars. Charged pions () are produced in nuclear collisions on the neutron star surface during active a…
Constraints on Bygone Nucleosynthesis of Accreting Neutron Stars
Zach Meisel, Alex Deibel
Nuclear burning near the surface of an accreting neutron star produces ashes that, when compressed deeper by further accretion, alter the star's thermal and compositional structure…
Late time cooling of neutron star transients and the physics of the inner crust
Alex Deibel, Andrew Cumming, Edward F. Brown +1
An accretion outburst onto a neutron star transient heats the neutron star's crust out of thermal equilibrium with the core. After the outburst the crust thermally relaxes toward e…
The thermal state of KS 1731-260 after 14.5 years in quiescence
Rachael L. Merritt, Edward M. Cackett, Edward F. Brown +7
Crustal cooling of accretion-heated neutron stars provides insight into the stellar interior of neutron stars. The neutron star X-ray transient, KS~1731260, was in outburst for…
Urca cooling pairs in the neutron star ocean and their effect on superbursts
Alex Deibel, Zach Meisel, Hendrik Schatz +2
An accretion outburst onto a neutron star deposits hydrogen-rich and/or helium-rich material into the neutron star's envelope. Thermonuclear burning of accreted material robustly p…
Ocean g-modes on transient neutron stars
Alex Deibel
The neutron star ocean is a plasma of ions and electrons that extends from the base of the neutron star's envelope to a depth where the plasma crystallizes into a solid crust. Duri…
A strong shallow heat source in the accreting neutron star MAXI J0556-332
Alex Deibel, Andrew Cumming, Edward F. Brown +1
An accretion outburst in an X-ray transient deposits material onto the neutron star primary; this accumulation of matter induces reactions in the neutron star's crust. During the a…
Magnetar giant flare oscillations and the nuclear symmetry energy
Alex T. Deibel, Andrew W. Steiner, Edward F. Brown
If the observed quasi-periodic oscillations in magnetar flares are partially confined to the crust, then the oscillation frequencies are unique probes of the nuclear physics of the…
