Cooling Delays from Iron Sedimentation and Iron Inner Cores in White Dwarfs
M. E. Caplan, I. F. Freeman, C. J. Horowitz +2
Do white dwarfs have inner cores made of iron? Neutron rich nuclei like Fe experience a net gravitational force and sediment toward the core. Using new phase diagrams and mo…
Nuclear fission chain reaction in cooling white dwarf stars
C. J. Horowitz, M. E. Caplan
The first solids that form as a white dwarf (WD) starts to crystallize are expected to be greatly enriched in actinides. Previously [PRL 126, 1311010] we found that these solids mi…
Precise Diffusion Coefficients for White Dwarf Astrophysics
M. E. Caplan, I. F. Freeman
Observations of galactic white dwarfs with Gaia have allowed for unprecedented modeling of white dwarf cooling, resolving core crystallization and sedimentary heating from neutron…
Crater Morphology of Primordial Black Hole Impacts
Almog Yalinewich, Matthew E. Caplan
In this work we propose a novel campaign for constraining relativistically compact MACHO dark matter, such as primordial black holes (PBHs), using the moon as a detector. PBHs of a…
Actinide crystallization and fission reactions in cooling white dwarf stars
C. J. Horowitz, M. E. Caplan
The first solids that form as a cooling white dwarf (WD) starts to crystallize are expected to be greatly enriched in actinides. This is because the melting points of WD matter sca…
