Accreting neutron stars (NS) can exhibit high frequency modulations in their light curves during thermonuclear X-ray bursts, known as burst oscillations. The frequencies can be offset from the spin frequency of the NS by several Hz, and can drift by 1–3 Hz. One possible explanation is a mode in the bursting ocean, the frequency of which would decrease (in the rotating frame) as the burst cools, hence explaining the drifts. Most burst oscillations have been observed during the H/He-triggered…

Surface Modes on Bursting Neutron Stars and X-Ray Burst Oscillations

Accreting neutron stars (NSs) often show coherent modulations during type I X-ray bursts, called burst oscillations. We consider whether a nonradial mode can serve as an explanation for burst

We present a comprehensive observational and theoretical analysis of the amplitudes and profiles of oscillations that occur during thermonuclear X-ray bursts from weakly magnetized neutron stars in

During a type I burst, the turbulent deflagration front may excite waves in the neutron star ocean and upper atmosphere with frequencies ω ~ 1 Hz. These waves may be observed as highly coherent flux

Thermonuclear Burst Oscillations

Burst oscillations, a phenomenon observed in a significant fraction of Type I (thermonuclear) X-ray bursts, involve the development of highly asymmetric brightness patches in the burning surface

On the Amplitude of Burst Oscillations in 4U 1636–54: Evidence for Nuclear-powered Pulsars

We present a study of 581 Hz oscillations observed during a thermonuclear X-ray burst from the low-mass X-ray binary (LMXB) 4U 1636-54 with the Rossi X-Ray Timing Explorer. This is the first X-ray

The Thermal Evolution following a Superburst on an Accreting Neutron Star

Superbursts are very energetic type I X-ray bursts discovered in recent years by long-term monitoring of X-ray bursters and are believed to be due to unstable ignition of carbon in the deep ocean of

Evolution of the bursting-layer wave during a type I X-ray burst

In a popular scenario due to Heyl, quasi-periodic oscillations (QPOs) which are seen during type I X-ray bursts are produced by giant travelling waves in the neutron star bursting layer. Piro and

Fast and slow magnetic deflagration fronts in Type I X-ray bursts

Type I X-ray bursts are produced by thermonuclear runaways that develop on accreting neutron stars. Once one location ignites, the flame propagates across the surface of the star. Flame propagation

Unstable Nonradial Oscillations on Helium-burning Neutron Stars

Material accreted onto a neutron star can stably burn in steady state only when the accretion rate is high (typically super-Eddington) or if a large flux from the neutron star crust permeates the
