A temperature scale of eV in the mass-radius relationship of white dwarfs of type DA
Jin Lim, Ji-Yu Kim, Maurice H. P. M. van Putten
The mass-radius relationship of white dwarfs (WDs) is one of their defining characteristics, largely derived from electron degeneracy pressure. We present a model-independent study…
