These are theoretical gravity limits, not measurements... and relies groupings of matter way beyond anything empirically stable.
After something a bit simpler, with some empirics? http://www.youtube.com/watch?v=egJhrvS2IGI
sound similar?
All you'd need would be for the pulsars of 47tuc to be binary pairs...

just an idea ;-)
spin ups, spin downs, fluctuations, outbursts, etc... all expected.... no need for 25% of C rotation or this other fantastic 'strange matter' that's never been seen. |
Problem is, Alex, how are you going to measure the gravitational field around the pulsar unless there's something in orbit about it. Or its surface gravity unless you have instruments sitting on its surface. Good luck with that!!!.
Your idea might be an explanation in some cases (only if the pulsars are close enough together to generate an enormous flux tube between their respective poles), but not in every case. However, it could just as easily be high energy electrons being whipped around along with the flux tubes within the magnetic fields of the pulsars...basically generating radio waves.
Plus, you have to remember, millisecond pulsars are part of binary systems, but the primary of those systems is either a giant star that's filled it's Roche Lobe and is spilling gas onto the pulsar, or a main sequence star in a very tight orbit around the pulsar and is being pulled apart. Most of those slower pulsars are loners. Most binary pulsars are in exceedingly tight orbits and have very quick orbital motions, but are themselves not necessarily in the millisecond category.
