JD3 – Neutron Stars: Timing in Extreme Environments

The space-time around Neutron Stars is indeed an extreme environment. Whether they are in accreting binary systems, isolated or in non-accreting binaries (perhaps with another Neutron Star), Neutron Stars provide a window onto physical processes not accessible by other means. In particular, the study of their time variability: pulsations, quasi-periodic oscillations, thermonuclear X-ray bursts, flares and giant-flares, pulsar glitches and pulse period variations, constitutes a valuable instrument to unveil those very same physical processes. Here we briefly summarize the most important results presented at Joint Discussion 3 of the XXVII IAU General Assembly.
