Constraining the Equation of State with Moment of Inertia Measurements

We estimate that the moment of inertia of star A in the recently discovered double pulsar system PSR J0737-3039 may be determined after a few years of observation to something like 10% accuracy. This would enable accurate estimates of the radius of the star and the presure of matter in the vicinity of 1 to 2 times the nuclear saturation density, which would in turn provide strong constraints on...

Constraining the neutron star equation of state using XMM - Newton

We have identified three possible ways in which future XMM-Newton observations can provide significant constraints on the equation of state of neutron stars. First, using a long observation of the neutron star X-ray transient Cen X–4 in quiescence one can use the RGS spectrum to constrain the interstellar extinction to the source. This removes this parameter from the X-ray spectral fitting of t...

Constraining the Dark Energy Equation of State with Cosmic Voids

Our universe is observed to be accelerating due to the dominant dark energy with negative pressure. The dark energy equation of state (w) holds a key to understanding the ultimate fate of the universe. The cosmic voids behave like bubbles in the universe so that their shapes must be quite sensitive to the background cosmology. Assuming a flat universe and using the priors on the matter density ...

The Pfgc Equation of State at the Age of Fourteen

The purpose of this paper was to review and report the recent advances and progress that have been achieved on the fourteen year old PFGC equation of state. This paper will also discuss the good (pros) and the bad (cons) of this equation of state. Emphasis will be made on the following categories:A. Prediction of the pure component PVT properties1. Hydrocarbons in particular n-alkanes2. Selecte...

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...
