Geodetic Precession in Binary Neutron Stars

The discovery of pulsars in 1967 marked the beginning of a new era in astrophysics. Besides studying pulsars as fascinating astrophysical objects in their own right, these sources serve as invaluable tools in the research of a large variety of physical and astrophysical problems. Studied subjects range from plasma and solid-state physics under extreme conditions to investigations of the interst...

Geodetic Precession in PSR B 1534 + 12

We present Arecibo observations of PSR B1534+12 which confirm previous suggestions that the pulse profile is evolving secularly. This effect is similar to that seen in PSR B1913+16, and is almost certainly due to general relativistic precession of the pulsar’s spin axis.

Geodetic Precession in PSR J 1141 – 6545

We present observations that show dramatic evolution of the mean pulse profile of the relativistic binary pulsar J1141–6545 over a period of five years. These data indicate that the spin axis of the pulsar is precessing due to relativistic spin-orbit coupling. Observations made between 1999 and 2004 with a number of instruments at the Parkes radio telescope demonstrate a steady, secular evoluti...

Geodetic precession or dragging of inertial frames?

In General Relativity the Principle of General Covariance allows one to describe phenomena by means of any convenient choice of coordinate system. In this paper it is shown that the geodetic precession of a gyroscope orbiting a spherically symmetric, nonrotating mass can be recast as a Lense-Thirring frame-dragging effect, in an appropriately chosen coordinate frame whose origin falls freely al...

Alfvén Wave-driven Supernova Explosion

We investigate the role of Alfvén waves in the core-collapse supernova (SN) explosion. We assume that Alfvén waves are generated by convections inside a proto-neutron star (PNS) and emitted from its surface. Then these waves propagate outwards and dissipate via nonlinear processes and heat up matter around a stalled prompt shock. To quantitatively assess the importance of this process for reviv...
