White dwarf cooling via gravity portals
arXiv:2001.06004 · doi:10.1103/PhysRevD.101.023017
Abstract
We investigate the impact of gravity portal to properties of white dwarfs, such as equation-of-state as well as cooling time. We find that the interaction between dark matter spin-zero bosons and electrons in the mean field approximation softens the equation-of-state, and the object coolers down slower compared to the usual case.
