Search for thermonuclear burst oscillations in the Swift/BAT data set
Frontiers in Astronomy and Space SciencesThis study comprehensively analyzes type I X-ray bursts observed by Swift/BAT from 2005 to April 2024 to search for X-ray burst oscillations (XBOs) in neutron star low-mass X-ray binaries.

Hydrogen-triggered X-Ray Bursts from SAX J1808.4−3658? The Onset of Nuclear Burning
The Astrophysical Journal, 2023 We present a study of weak, thermonuclear X-ray bursts from the accreting millisecond X-ray pulsar SAX J1808.4−3658. We focus on a burst observed with the Neutron Star Interior Composition Explorer on 2019 August 9, and describe a similar burst observed ...

Anisotropy of the sky distribution of gamma-ray bursts [PDF]
, 1998 The isotropy of gamma-ray bursts collected in current BATSE catalog is studied. It is shown that the quadrupole term being proportional to \sim sin 2b sin l is non-zero with a probability of 99.9%. The occurrence of this anisotropy term is then confirmed

X-Ray Bursting Neutron Stars [PDF]
Symposium - International Astronomical Union, 1987 The maximum peak luminosity of the X-ray bursts from a burster is most likely interpreted as the Eddington luminosity of a helium-rich envelope surrounding a neutron star. If this interpretation is true, we can obtain a relation between the mass and the radius of the neutron star in terms of the maximum effective temperature of bursts.

The Game of Life on a Magnetar Crust: From Gamma-Ray Flares to FRBs
The Astrophysical Journal Letters, 2023 This Letter presents a model to unify the diverse range of magnetar activity, through the building and release of elastic stress from the crust. A cellular automaton drives both local and global yielding of the crust, leading to braiding of coronal loops

A unified model of short and long gamma-ray bursts, X-ray–rich gamma-ray bursts, and X-ray flashes [PDF]
, 2005 We propose a possible unified model of short and long gamma-ray bursts (GRBs), X-ray–rich GRBs, and X-ray flashes. The jet of a GRB is assumed to consist of many emitting sub-shells, that is called sub-jet emissions (i.e., an inhomogeneous jet model ...

Monster Radiative Shocks in the Perturbed Magnetospheres of Neutron Stars
The Astrophysical Journal, 2023 Magnetospheres of neutron stars can be perturbed by star quakes, interaction in a binary system, or sudden collapse of the star. The perturbations are typically in the kilohertz band and excite magnetohydrodynamic waves.

MAXI observations of long X-ray bursts [PDF]
Publications of the Astronomical Society of Japan, 2016 Abstract We report nine long X-ray bursts from neutron stars, detected with the Monitor of All-sky X-ray Image (MAXI). Some of these bursts lasted for hours, and hence are qualified as superbursts, which are prolonged thermonuclear flashes on neutron stars and are relatively rare events.

Estimation of plasma parameters of X-pinch with time-resolved x-ray spectroscopy
Matter and Radiation at Extremes, 2023 We estimate the parameters of a Cu plasma generated by an X-pinch by comparing experimentally measured x-rays with synthetic data. A filtered absolute extreme ultraviolet diode array is used to measure time-resolved x-ray spectra with a spectral ...
