The galactic distribution and physical nature of X-ray transient sources is investigated. Two types of transients are considered. The observational data on 41 X-ray transient sources are given, and the average parameters of hard and soft X-ray transients are estimated.

X-ray variability in transient X-ray sources
Il Nuovo Cimento Della Società Italiana Di Fisica C, 1990The X-ray variability of transient X-ray binaries is analyzed in terms of the orbital motion of the neutron star, centrifugal inhibition of accretion and of the variable moss loss rate due to activity of the optical counterpart. The systems A0535+26 and V0332+53 are studied in this respect.

The periodic transient X-ray sources
Nature, 1975THE transient X-ray sources Ariel 1118–61 and Ariel 0535 + 26 have periods of 405 s (ref. 1) and 114 s (ref. 2) respectively. Rappaport and McClintock3 reported the discovery of a 283-s period in the X-ray binary 3U0900–40 (a ‘continuous’ source) which is known to have an orbital period Porb = 8.95 d.

BATSE observations of transient hard X-ray sources
AIP Conference Proceedings, 1994Many transient sources have been detected and monitored by the Burst and Transient Source Experiment (BATSE) since launch using the Earth occultation technique. These include x‐ray novae, pulsars, and other galactic sources. We present preliminary results of the temporal and spectral characteristics for seven transients which are potentially black hole

IN the eccentric-orbit binary model1,2, a compact object is in an eccentric orbit around a more massive, slightly evolved star. If the compact object accretes mass from the stellar wind of the normal star, the accretion rate is time dependent, so that the resulting X-ray emission would show a maximum at periastron (in the absence of absorption ...

A rocket observation of cosmic soft X-rays suggests the existence of transient, recurrent soft X-ray sources which are found variable during the flight time of the rocket. Some of the soft X-ray sources thus far reported are considered to be of this time. These sources are listed in Table I, and their positions are shown in Figure 2.

Abstract One of the most striking results of Ariel 5 has been the large number of transient sources which has been observed, including what is probably a new type which is relatively short-lived and one near the Galactic Centre which is also probably distinct from the others since it was also observed as a radio source.
