They have shown that the compact object orbiting the
23-millisecond pulsar PSR J0737-3039A with a period of just 2.4
hours is not only, as suspected, another neutron star but is
also a detectable pulsar, PSR J0737-3039B, that is rotating once
every 2.8 seconds.
NDT One would wonder about tidal accelerations. If the Moon gets a
NDT "boost" from Earth's tides, does "neutronium" have any give that
NDT would allow similar angular momentum transfer. Anyone know what
NDT the 2.4 hour period is doing secularly?
I don't know if this has been measured yet, although it is
expected to increase with time by the emission of gravitational
radiation (...).
NDT I guess I don't understand why it would *increase*. Transfer of
NDT angular momentum from the Earth to the Moon increases the
NDT period. *Loss* of angular momentum to the Universe at large
NDT would make the period *shorter*, no? Did you mean to say the
NDT period would decrease, not increase?
Umm, yes, that's what I meant. Thanks for catching that.
Tidal effects shouldn't be that important, though. The two neutron
stars are about 10 km in diameter. They are separated by about 1
million km.
NDT Assuming we have space travel, and are situated about 10AU out
NDT from the mass center of such a system, and about 1AU above its
NDT ecliptic, what do you imagine we could see? Assuming the
NDT radiation didn't kill us, of course... Could we see the sizes
NDT of these bodies, would there be visible light?
Take a look at one of my answers on MadSci, URL:

Does that address your question?
