TL;DR: In this paper, the authors carried out optical observations of the field of the X-ray pulsator RX J0806.3+1527 and found that a blue V = 21.1 star was the only object consistent with the position.

TL;DR: In this article, the relativistic precession model was used to test general relativity against those alternative theories of gravity which predict deviations from the classical theory in the strong-field regime, and showed that detection of quasi-periodic oscillations with the expected sensitivity of the proposed ESA M-class mission LOFT would set the most stringent constraints on the parameter space of this theory.

TL;DR: In this paper, the Lense-Thirring precession frequency for point masses in the Kerr metric for arbitrary black hole mass and specific angular momentum was computed for the point masses at or close to the innermost stable orbit.

TL;DR: The results of a recent XMM-Newton Target of Opportunity (TOMO) observation of the anomalous X-ray Pulsar 1E 1048.1-5937 were reported in this paper.

TL;DR: In this article, the torque equation of the accreting pulsar was solved within the framework of the magnetically threaded-disk scenario, and three classes of solutions, corresponding to different values of the magnetic field, were mathematically allowed.
