A hard X-ray observation of the 1979 outburst of Centaurus X-4 with the frano-soviet Signe 2 MP ( PROGNOZ) satellite experiment.
Abstract
In 1979 May, a collimated detector in the Signe 2 MP experiment aboard the Prognoz 7 satellite detected intense 13 - 163 keV X-ray emission from the source Centaurus X-4. This was the first time that high-energy X-ray emission was observed from this object, which up to now has been categorized as a type I soft X-ray burster. The light curve of the outburst is presented, as well as the hard X-ray spectrum at various times during the outburst.
