Take the tour ×  In what part of the spectrum is it radiating?
In the infrared, in the microwave? Or is not radiating anymore
at all?  In russian:  Чему сейчас равна температура поверхности
и ядра нейтронной звезды, которая образовалась 12 миллиардов лет
назад? В каком диапазоне она сейчас излучает? В инфракрасном,
микроволновом? Или не излучает вообще?  share|improve this

Translation into English: "What is the temperature of the
surface and core of a neutron star formed 12 billion years ago
now equal to? In what part of the spectrum is it radiating? In
the infrared, in the microwave? Or is not radiating anymore at
all? –  Mark C Nov 10 '10 at 19:25 Another question is, what
suppose to happen with neutron star on long run ? what makes it
burn, what kind of fusion/decay is happening there ? What if it
cools, then what degenerated matter looks like after it cools ?
will the gravitational equilibrium be ruined after some burn
time ? how it explodes if it
