Dark matter could be composed of compact dark objects (CDOs). We find that the oscillation of CDOs inside neutron stars can be a detectable source of gravitational waves (GWs). The GW strain amplitude depends on the mass of the CDO, and its frequency is typically in the range 3-5 kHz as determined by the central density of the star. In the best cases, LIGO may be sensitive to CDO masses greater than or of order 10(-8) M-circle dot.

Actinide Crystallization and Fission Reactions in Cooling White Dwarf Stars

C. J. Horowitz, M. E. Caplan

Summary: Research suggests that as a white dwarf starts to crystallize, the first solids formed may be highly enriched in actinides, potentially leading to a fission chain reaction and ignition of carbon burning, resulting in a thermonuclear supernova explosion. This mechanism could offer an explanation for supernovae with sub-Chandrasekhar ejecta masses and short delay times.

Implications of PREX-2 on the Equation of State of Neutron-Rich Matter

Brendan T. Reed, F. J. Fattoyev, C. J. Horowitz, J. Piekarewicz

Summary: Laboratory experiments sensitive to the equation of state of neutron rich matter in the vicinity of nuclear saturation density provide crucial data connecting terrestrial experiments to astronomical observations. The neutron skin thickness of Pb-208 further constrains the density dependence of the symmetry energy. The impact of a stiff symmetry energy on critical neutron-star observables is studied.

Modeling the Galactic Neutron Star Population for Use in Continuous Gravitational-wave Searches

Brendan T. Reed, Alex Deibel, C. J. Horowitz

Summary: Searches for continuous gravitational waves from unknown Galactic neutron stars provide limits on the shapes of neutron stars. Using a simple model of the spatial and spin distribution of Galactic neutron stars, the total number of neutron stars probed can be estimated, aiding in optimizing future searches with improved sensitivity. Third-generation GW detectors may greatly increase the number of neutron stars probed to a given ellipticity.

Summary: Precision determinations of the beam-normal single spin asymmetries (A(n)) in the elastic scattering of 0.95 and 2.18 GeV electrons off C-12, Ca-40, Ca-48, and Pb-208 were reported. The measurement results for Ca-40 and Ca-48 are similar to that of C-12, consistent with expectations and validating the theoretical calculations for nuclei with Z ≤ 20. However, the A(n) measurements for Pb-208 show significant disagreement with the results for Z ≤ 20 nuclei, indicating the need for further investigation.

Detectability of subsolar mass neutron stars through a template bank search

Ananya Bandopadhyay, Brendan Reed, Surendra Padamata, Erick Leon, C. J. Horowitz, Duncan A. Brown, David Radice, F. J. Fattoyev, J. Piekarewicz

Summary: We investigate the detectability of gravitational-wave signals from subsolar-mass binary neutron star systems using current ground-based detectors. Finite size effects and lower merger frequencies of neutron stars significantly impact the sensitivity of these detectors. By simulating a matched-filter search with injected signals, we calculate the reduction in sensitivity and obtain an upper limit on the merger rate. The discovery of low-mass neutron stars would provide new insights into their formation mechanisms and constrain dense nuclear matter.

Nuclear fission reaction simulations in compact stars

Alex Deibel, M. E. Caplan, C. J. Horowitz

Summary: Scientists simulated the reaction network of actinide-rich solids in a cooling white dwarf and found that under moderate uranium enrichment, neutron capture can breed additional fissile nuclei, leading to the fission of a significant fraction of U and Th nuclei during the chain reaction.

Cooling Delays from Iron Sedimentation and Iron Inner Cores in White Dwarfs

M. E. Caplan, I. F. Freeman, C. J. Horowitz, A. Cumming, E. P. Bellinger

Summary: This study suggests that white dwarfs may have inner cores made of iron which separate into mesoscopic crystallites. The associated cooling delays could be up to a Gyr for low-mass white dwarfs but are only around 0.1 Gyr for massive white dwarfs. The heating from this mechanism is insufficient to fully explain certain phenomena.
