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…
Age-Dating Red Giant Stars Associated with Galactic Disk and Halo Substructures
Samuel K. Grunblatt, Joel C. Zinn, Adrian M. Price-Whelan +12
The vast majority of Milky Way stellar halo stars were likely accreted from a small number (3) of relatively large dwarf galaxy accretion events. However, the timing of t…
Asteroseismic Inference of the Central Structure in a Subgiant Star
Earl P. Bellinger, Sarbani Basu, Saskia Hekker +2
Asteroseismic measurements enable inferences of the underlying stellar structure, such as the density and the speed of sound at various points within the interior of the star. This…
