Circular polarization in the optical afterglow of GRB 121024A

K. Wiersema, S. Covino, K. Toma +37

Gamma-ray bursts (GRBs) are most probably powered by collimated relativistic outflows (jets) from accreting black holes at cosmological distances. Bright afterglows are produced wh…

Quasi-Periodic Oscillations in Short Recurring Bursts of the magnetars SGR 1806-20 and SGR 1900+14 Observed With RXTE

D. Huppenkothen, L. M. Heil, A. L. Watts +1

Quasi-periodic oscillations (QPOs) observed in the giant flares of magnetars are of particular interest due to their potential to open up a window into the neutron star interior vi…

Intermittency and Lifetime of the 625 Hz QPO in the 2004 Hyperflare from the Magnetar SGR 1806-20 as evidence for magnetic coupling between the crust and the core

Daniela Huppenkothen, Anna L. Watts, Yuri Levin

Quasi-periodic oscillations (QPOs) detected in the 2004 giant flare from SGR 1806-20 are often interpreted as global magneto-elastic oscillations of the neutron star. There is, how…

Oblique magnetic fields and the role of frame dragging near rotating black hole

V. Karas, O. Kopacek, D. Kunneriath +1

Magnetic null points can develop near the ergosphere boundary of a rotating black hole by the combined effects of strong gravitational field and the frame-dragging mechanism. The i…

Discovery of the near-infrared counterpart to the luminous neutron-star low-mass X-ray binary GX 3+1

Maureen van den Berg, Jeroen Homan, Joel K. Fridriksson +1

Using the High Resolution Camera onboard the Chandra X-ray Observatory, we have measured an accurate position for the bright persistent neutron-star X-ray binary and atoll source G…

Regular and Chaotic Motion in General Relativity: The Case of a Massive Magnetic Dipole

Ondřej Kopáček, Jiří Kovář, Vladimír Karas +1

Circular motion of particles, dust grains and fluids in the vicinity of compact objects has been investigated as a model for accretion of gaseous and dusty environment. Here we fur…

Inducing chaos by breaking axial symmetry in a black hole magnetosphere

O. Kopáček, V. Karas

While the motion of particles near a rotating, electrically-neutral (Kerr), and charged (Kerr--Newman) black hole is always strictly regular, a perturbation in the gravitational or…

Quasi-Periodic Oscillations in Short Recurring Bursts of the Soft-Gamma Repeater J1550-5418

Daniela Huppenkothen, Caroline D'Angelo, Anna L. Watts +11

The discovery of quasi-periodic oscillations (QPOs) in magnetar giant flares has opened up prospects for neutron star asteroseismology. The scarcity of giant flares makes a search…

The Evolution of Compact Binary Star Systems

Konstantin Postnov, Lev Yungelson

We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Mergings of compact binary stars are exp…

The Galactic center X-ray transients AX J1745.6-2901 and GRS 1741-2853

N. Degenaar, R. Wijnands, M. T. Reynolds +3

AX J1745.6-2901 and GRS 1741-2853 are two transient neutron star low-mass X-ray binaries that are located within ~10' from the Galactic center. Multi-year monitoring observations w…

Distinguishing between spot and torus models of high-frequency quasiperiodic oscillations

V. Karas, P. Bakala, G. Torok +8

In the context of high-frequency quasi-periodic oscillation (HF QPOs) we further explore the appearance of an observable signal generated by hot spots moving along quasi-elliptic t…
