The Shear Viscosity and Thermal Conductivity of Nuclear Pasta
C. J. Horowitz, D. K. Berry
We calculate the shear viscosity and thermal conductivity of a nuclear pasta phase in neutron star crusts. This involves complex non-spherical shapes. We use semiclassical…
Thermal conductivity and phase separation of the crust of accreting neutron stars
C. J. Horowitz, O. L. Caballero, D. K. Berry
Recently, crust cooling times have been measured for neutron stars after extended outbursts. These observations are very sensitive to the thermal conductivity of the crust and…
Fusion of neutron rich oxygen isotopes in the crust of accreting neutron stars
C. J. Horowitz, H. Dussan, D. K. Berry
Fusion reactions in the crust of an accreting neutron star are an important source of heat, and the depth at which these reactions occur is important for determining the temperatur…
The Thermal Regulation of Gravitational Instabilities in Protoplanetary Disks. IV. Simulations with Envelope Irradiation
Kai Cai, Richard H. Durisen, Aaron C. Boley +2
It is generally thought that protoplanetary disks embedded in envelopes are more massive and thus more susceptible to gravitational instabilities (GIs) than exposed disks. We prese…
Phase separation in the crust of accreting neutron stars
C. J. Horowitz, D. K. Berry, E. F. Brown
Nucleosynthesis, on the surface of accreting neutron stars, produces a range of chemical elements. We perform molecular dynamics simulations of crystallization to see how this comp…
Neutrino Scattering in Heterogeneous Supernova Plasmas
O. L Caballero, C. J. Horowitz, D. K. Berry
Neutrinos in core collapse supernovae are likely trapped by neutrino-nucleus elastic scattering. Using molecular dynamics simulations, we calculate neutrino mean free paths and ion…
The Thermal Regulation of Gravitational Instabilities in Protoplanetary Disks III. Simulations with Radiative Cooling and Realistic Opacities
A. C. Boley, A. C. Mejia, R. H. Durisen +3
This paper presents a fully three-dimensional radiative hydrodymanics simulation with realistic opacities for a gravitationally unstable 0.07 Msun disk around a 0.5 Msun star. We a…
Nonuniform Neutron-Rich Matter and Coherent Neutrino Scattering
C. J. Horowitz, M. A. Perez-Garcia, J. Carriere +2
Nonuniform neutron-rich matter present in both core-collapse supernovae and neutron-star crusts is described in terms of a semiclassical model that reproduces nuclear-matter proper…
The Thermal Regulation of Gravitational Instabilities in Protoplanetary Disks II. Extended Simulations with Varied Cooling Rates
Annie C. Mejia, Richard H. Durisen, Megan K. Pickett +1
In order to investigate mass transport and planet formation by gravitational instabilities (GIs), we have extended our 3-D hydrodynamic simulations of protoplanetary disks from a p…
