The Moment of Inertia of the Binary Pulsar J0737-3039a: Constraining the Nuclear Equation of State
We construct numerical models of the newly discovered binary pulsar J0737-3039A, both with a fully relativistic, uniformly rotating, equilibrium code that handles arbitrary spins and in the relativistic, slow-rotation approximation. We compare results for a representative sample of viable nuclear equations of state (EOS) that span three, qualitatively different, classes of models for the descri...
متن کاملDynamical determination of the quadrupole mass moment of the double pulsar PSR J0737-3039A/B system
In this paper we dynamically determine the quadrupole mass moment Q of the two-pulsars system PSR J0737-3039A/B by analyzing the orbital period of the relative motion occurring along a close 2.4-hr, elliptic orbit. By using the timing measurement of sin i, we obtain Q = (−7.7 ± 3.9) × 10 kg m. The major source of systematic error is the uncertainty in the semimajor axis a mainly due, in turn, t...
متن کاملProspects for measuring the moment of inertia of pulsar J0737-3039A
Here we consider the possibility−envisaged bymany authors as feasible in the near future−of measuring at 10% or better the moment of inertia I of the pulsar J0737-3039A via the gravitomagnetic spin-orbit periastron precession (analogous to the Lense-Thirring pericentre precession in the case of a test-particle orbiting a central spinning mass). Such a gravitomagnetic effect is expected to be of...

متن کاملThe Formation of the Double Pulsar PSR J0737−3039A/B
Recent timing observations of the double pulsar J0737−3039A/B have shown that its transverse velocity is extremely low, only 10 km/s, and nearly in the Plane of the Galaxy. With this new information, we rigorously re-examine the history and formation of this system, determining estimates of the pre-supernova companion mass, supernova kick and misalignment angle between the preand post-supernova...
