Prospects for measuring the moment of inertia of pulsar PSR J0737-3039A

Abstract

Here we consider the possibility of measuring at 10% or better the moment of inertia I of the J0737-3039A via the gravitomagnetic spin-orbit periastron precession. It turns out that the prospect of measuring the moment of inertia of PSR J0737-3039A at 10% accuracy or better seems unlikely given the limitations to the precision with which the system's basic binary and post-Keplerian parameters can be measured via radio timing.Comment: LaTex2e, 5 pages (Elsevier two-column style), 1 table, no figures.
