EXOSAT observations of 3A 1954+319.
Abstract
An EXOSAT observation of 3A 1954+319 [4U 1954+31] revealed a source with a hard X-ray spectrum and a light curve dominated by flaring behaviour on timescales of 1 - 10 minutes. Spectral variations were also observed on these timescales. No evidence was found for the existence of coherent pulsations. The X-ray properties indicate a high mass system accreting from a highly inhomogeneous medium.
