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.

Gamma-ray production by particles escaping from a pulsar into the surrounding nebula is considered. The gamma-ray emission decreases with time and such pulsar-nebula complexes will be observed as transient sources.

Constraints on Minute-Scale Transient Astrophysical Neutrino Sources [PDF]
Physical Review Letters, 2019 High-energy neutrino emission has been predicted for several short-lived astrophysical transients including gamma-ray bursts (GRBs), core-collapse supernovae with choked jets and neutron star mergers. IceCube's optical and X-ray follow-up program searches for such transient sources by looking for two or more muon neutrino candidates in directional ...

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 ...

On the Radiation from Transient Light Sources
Proceedings of the Physical Society. Section A, 1949A theoretical treatment is given of the problem of analysing the radiation from transient light sources in the form of clouds of incandescent particles. Recently a method of correlating this radiation with various physical parameters has been suggested by E. F. Caldin.

The Source and Nature of Transient Surges
IEEE Transactions on Industry Applications, 1977Sources of transient voltages or surges due to various phenomena normal to the power station environment are described along with typical waveforms and other parameters of the surges coupled into control circuits. The mechanism by which surges are generated by switching of inductive devices in low voltage control circuits is described in detail.

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.

Hydraulic Transients: A Seismic Source in Volcanoes and Glaciers
Science, 1979A source for certain low-frequency seismic waves is postulated in terms of the water hammer effect. The time-dependent displacement of a water-filled subglacial conduit is analyzed to demonstrate the nature of the source. Preliminary energy calculations and the observation of hydraulically generated seismic radiation from a dam indicate the ...
