X-ray burst ignition location on the surface of accreting X-ray pulsars: can bursts preferentially ignite at the hotspot? [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Hotspots on the surface of accreting neutron stars have been directly observed via pulsations in the light curves of X-ray pulsars. They are thought to occur due to magnetic channelling of the accreted fuel to the neutron star magnetic poles.

The Thermonuclear X-Ray Bursts of 4U 1730–22 [PDF]
The Astrophysical Journal, 2022 Abstract We present observations of the historic transient 4U 1730–22 as observed with the Neutron Star Interior Composition Explorer (NICER). After remaining in quiescence since its 1972 discovery, this X-ray binary showed renewed outburst activity in 2021 and 2022.

Observations of X-ray Burst Sources [PDF]
Symposium - International Astronomical Union, 1987 Recent observational results on X-ray bursts and burst sources are reviewed. Two distinct types of bursts, Type I and Type II bursts, are discussed in relation to the mass and radius of neutron stars and to the problems of unusual mass accretion in some burst sources.

Reanalysis of the X-Ray-burst-associated FRB 200428 with Insight-HXMT Observations
The Astrophysical Journal, 2023 A double-peak X-ray burst from the Galactic magnetar SGR J1935+2154 was discovered to be associated with the two radio pulses of FRB 200428 separated by 28.97 ± 0.02 ms.

A Model for Bursting X-Ray Sources [PDF]
Highlights of Astronomy, 1977 A model given by Henriksen and Chia (1972) for short duty cycle X-ray flare sources has been extended by Henriksen (1976), and applied to the recently discovered X-ray bursters. We use their notation here unless otherwise indicated. The model envisages a rapidly rotating magnetic white dwarf or neutron star located in a dense stream or cloud of gas ...

287— The X-Ray Afterglows of Short Gamma-Ray Bursts [PDF]
, 2021 Light curves of the X-ray afterglow from 81 short gamma-ray bursts, from 2005 to 2018, were obtained from the Swift/XRT catalog. The light curves were fit with single power-law and double-power law models using the emcee library in Python and sorted into

Solar Physics, 1985 The major results from SMM are presented as they relate to our understanding of the energy release and particle transportation processes that lead to the high-energy X-ray aspects of solar flares. Evidence is reviewed for a 152–158 day periodicity in various aspects of solar activity including the rate of occurrence of hard X-ray and gamma-ray flares ...

X-ray Bursts Produced By Laboratory Sparks In Air [PDF]
, 2005 X-ray observations were made during fourteen 1.5 to 2.0 m high-voltage discharges in air produced by a 1.5 MV Marx circuit. All 14 discharges generated x-rays in the ∼30 to 150 keV range.
