Neutron star temperature and cooling

    Is there a well-established theory for temperature and cooling processes of neutron stars as a function of time?

    Well, in general relativity, einstein theorized the existence of gravitational waves. Many astrophysicists have attributed the decreases of a neutron stars angular momentum to this "gravitational radiation".

    Observational evidence consists of timing the intervals of each pulse from a pulsar, which tells us its rotational period. After monitoring it for a while (weeks? months? years?), the observing will record a consistent decay in it rotational energy. These observations are consistent with einstein's theory of general relativity, and almost confirm the existence of gravitational waves.

    I think you misunderstand the topic of the thread. :biggrin:

    Oh. Were we supposed to just supply an article like tom did?

    and my spelling was atrocious in that post...

    well, not exactly. It was that the OP asked for theories on neutron star temperature and cooling

    not gravitational radiation or the rotational rates of neutron stars

    As Shishkabob said, the topic was about the temperature and cooling of a neutron star, which has significant amounts of heat when it is formed. Gravitational waves are another topic altogether. No worries!
