White dwarf stars: electron-degenerate stellar remnants. Claims about their structure, cooling, atmospheres, mass-radius relation, binaries and Type Ia progenitors, and their role as targets or environments in astrophysical scenarios (e.g., interactions with high-energy particles or captured objects) belong here; neutron stars and other compact objects do not.

Ultra-high-energy cosmic rays strike white dwarfs and neutron stars at astrophysically significant rates.

In scenarios with more than six spacetime dimensions, only white dwarfs above about 1.1 solar masses can stop neutral TeV-scale black holes.
