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. forward contract vs hedgeMost observed white dwarfs have relatively high surface temperatures, between 8,000 K and 40,000 K. A white dwarf, though, spends more of its lifetime at cooler temperatures than at hotter temperatures, so we should expect that there are more cool white dwarfs than hot white dwarfs.
