On the specta of X-ray bursters: Expansion and contraction stages
The Astrophysical Journal, 1994 The theory of spectral formation during the explosion and contraction stages of X-ray bursters, which include the effects of Computonization and free-free absorption and emission, is described. Analytical expressions are provided for color ratios, and the spectral shape is given as a function of input parameters, elemental abundance, neutron star mass ...

X-ray bursters and the x-ray sources of the galactic bulge [PDF]
Space Science Reviews, 1981 An attempt is made to distill from observational and theoretical information on the galactic bulge X-ray sources in general, and on the X-ray burst sources in particular, those aspects which seem to have the greatest relevance to the understanding of these sources.

Discovery of the X-ray burster SAX J1752.3-3138 [PDF]
Astronomy & Astrophysics, 2001 During a 50 ks monitoring observation of the Galactic bulge performed in September 1999 by the Wide Field Cameras on board the BeppoSAX satellite, an X-ray burst was detected from a sky position ~3 degrees off the Galactic centre. No previously known X-ray sources are located within the position error circle of the observed burst.

Optical candidates for two X-ray bursters and an X-ray pulsar [PDF]
Nature, 1977 Faint blue stars are suggested as the optical counterparts of the X-ray bursters 4U (MXB) 1636-53 and 4U (MXB) 1735-44 as well as the 7-sec X-ray pulsar 4U 1626-67. The candidate stars have large UV excesses and were discovered well within the 20- and 30-arcsec error radii determined with the rotating modulation collimator aboard SAS 3.

eRASSt J040515.6 − 745202, an X-ray burster in the Magellanic Bridge
Astronomy & Astrophysics, 2023 Context. During the third all-sky survey (eRASS3), eROSITA, the soft X-ray instrument aboard Spectrum-Roentgen-Gamma, detected a new hard X-ray transient, eRASSt J040515.6 − 745202, in the direction of the Magellanic Bridge. Aims. We arranged follow-up observations and searched for archival data to reveal the nature of the transient. Methods.

Simulations of X-ray bursts and superbursts [PDF]
, 2015 Observations of neutron star in binary systems provide powerful constrains on the physics at the surface of neutron stars. During the accretion of matter from the companion star, periodic nuclear explosion are triggered in the outer layers of the neutron

The infrared counterpart of the X-ray burster KS 1731–260 [PDF]
Astronomy & Astrophysics, 2002 We present JK' infrared images of the X-ray transient KS 1731--260, obtained in 1997 and in 1998 with IRAC2b at the ESO/MPI 2.2-m telescope at La Silla. Using as a reference the recent Chandra position, we confirm the identification of the X-ray source with the previously proposed counterpart (Wijnands et al.

Fast Oscillations in Variable X-Ray Sources and X-Ray Bursters [PDF]
International Astronomical Union Colloquium, 1983 ABSTRACTThe properties of coherent oscillations with periods of tens of milliseconds that have been observed in seven variable X-ray sources and bursters are reviewed. Theoretical models for the generation of the oscillations are discussed. Difficulties with a magnetic rotator model are indicated.

Broadband observations of the X-ray burster 4U1705-44 withBeppoSAX [PDF]
Astronomy & Astrophysics, 2016 4U 1705-44 is one of the most-studied type I X-ray burster and Atoll sources. This source represents a perfect candidate to test different models proposed to self-consistently track the physical changes occurring between different spectral states because it shows clear spectral state transitions.
