X-ray transient sources

Astrophysics and Space Science, 1979
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.

Constraints on Minute-Scale Transient Astrophysical Neutrino Sources [PDF]

open access: yesPhysical 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 ...

Transient gamma-ray sources

Proceedings of the Indian Academy of Sciences - Section A, 1971
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.

Transient X-ray sources

Nature, 1975
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 ...
