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…
Nuclear fission reaction simulations in compact stars
Alex Deibel, M. E. Caplan, C. J. Horowitz
Type-Ia supernovae (SN Ia) are powerful stellar explosions that provide important distance indicators in cosmology. Recently, we proposed a new SN Ia mechanism that involves a nucl…
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…
Carbon Isotope Ratios in M10 Giants
Z. G. Maas, J. M. Gerber, Alex Deibel +1
We measured carbon abundances and the ratio in 31 giant branch stars with previous CN and CH band measurements that span -2.33 M …
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…
Direct Three-body Triple- in Helium Novae
Ryan Connolly, Alex Deibel, Edward F. Brown
In AM CVn binaries, a white dwarf primary accretes material from a helium-rich white dwarf or stellar companion. The unstable ignition of nuclear burning via the reaction in a…
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…
Strong neutrino cooling by cycles of electron capture and decay in neutron star crusts
Hendrik Schatz, Sanjib Gupta, Peter Möller +9
The temperature in the crust of an accreting neutron star, which comprises its outermost kilometer, is set by heating from nuclear reactions at large densities, neutrino cooling, 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…
The Orbital Structure of Triaxial Galaxies with Figure Rotation
Alex T. Deibel, Monica Valluri, David Merritt
We survey the properties of all orbit families in the rotating frame of a family of realistic triaxial potentials with central supermassive black holes (SMBHs). In such galaxies, m…
