How hot are white dwarf stars

WebAnother curious property of white dwarfs is that the more mass they have, the smaller they are. The Chandrasekhar limit of around 1.4 solar masses is the theoretical upper limit to the mass a white dwarf can have and still … WebAlthough neutron stars produce no heat, they are still hotter than white dwarf stars. At the core of a white dwarf, the temperature at birth is around 180,000 degrees Fahrenheit. At the core of a neutron star at birth, it is around 1.8 million degrees Fahrenheit. Neutron stars are the only stars with a higher density than white dwarfs.
