Possible models for some transient X-ray sources

Research output: Contribution to journal › Article › peer-review

Abstract

A TRANSIENT X-ray source flared up in Centaurus during December 1974 and was observed by the satellite Ariel V in the energy interval 3-30 keV (refs 1 and 2) Within a few days the source increased in intensity to a peak of 0.02 photons cm^-2 s^-1 keV^-1. After reaching a maximum, the intensity decayed with an e-folding time of about 7 d. About one month after the first detection the intensity had fallen by a factor ≳5. No further observations have yet been reported.
