X-Ray Spectra of Various Bursts from the Rapid Burster
Astrophysics and Space Science, 1986About 20 type-I bursts and 3000 type-II bursts were observed with Tenma and Hakucho in 1983. Spectral evolutions were analyzed for both types of bursts and results are presented.

A disc-reflected component in the spectra of X-ray bursters
Monthly Notices of the Royal Astronomical Society, 1991An argument is presented to the effect that a disk-reflected component should be present in the spectra of X-ray bursts and is best seen just after the burst peak when the reflected photons, delayed by their passage to the site of reflection, appear in stronger contrast to the fast-declining primary emission from the cooling neutron star.

IR flashes from the X-ray rapid burster
Nature, 1980We confirm here the report of Kulkarni et al.1 who discovered IR bursts from the X-ray rapid burster, MXB1730–335. We observed two bursts at 2.2 µm, each of energy ∼1031 J, and a new feature; several bright, brief flashes (Δt< 1 s) superimposed on the burst continuum. The brevity, luminosity and inferred brightness temperature of the flashes (TB≳1010K)

Observational evidence for the binary model of X-ray bursters
Advances in Space Research, 1983Abstract Most, but not all, theoretical models of X-ray bursters require a binary system consisting of a mass donating star and a neutron star. The observational evidence in support of this model, however, is both indirect and meager. We have detected absorption dips in the X-ray spectrum of the Burster MXB 1916-05 with the IPC and the MPC on the ...

Globular Cluster Winds Driven by X-Ray Bursters
Publications of the Astronomical Society of Japan, 1993Abstract As a removal mechanism of gas from a globular cluster, we propose a globular cluster wind which is driven by X-ray bursters embedded in the central region of the globular cluster. Energetically, a single X-ray burster can remove gas from a typical globular cluster, while about ten X-ray bursters are required to evacuate gas from

The luminosity oscillation of X-ray bursters and recurrent novae
Astrophysics and Space Science, 1987‘Thermo-mechanical’ oscillations of a radiating spherically-symmetric shell containing a fermion gas (i.e., oscillation where only mechanical, thermodynamical, and eventually radiation phenomena are taken into account) are studied. With a reasonable choice of the three relevant parameters all other observational data are similar to the ones of X-ray ...

ANS observations on the X-ray burster MXB1730—335
Nature, 1976A NEW type of time variability of cosmic X-ray sources (‘bursters’) was discovered from Astronomical Netherlands Satellite (ANS) observations on the source 3U1820–30, associated with the globular cluster NGC6624 (refs 1, 2). These X-ray bursts are characterised by a rapid rise in flux ( ∼ 0.5 s) to a relative intensity comparable to the Crab Nebula ...

Acoustic waves in the extended atmospheres of X-ray bursters
Advances in Space Research, 1995Abstract A possible sound origin for the second range photospheric oscillations detected in the X-ray bursting sources 1608−522 and 2127+119 is suggested. Basing on the recent models of radiatively driven winds from neutron stars during powerful, super-Eddington thermonuclear bursts, it is shown that standing sound waves propagating in expanding ...
