摘要：
We investigate the impact of the gravity portal on the properties of white dwarfs, such the as equation of state and the 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 objects cool down more slowly compared to the usual case.
