Scientific paper

The authors report the detection of two X-ray bursts from GX 17+2; a short one (lasting about 10 s), and a long one (which lasted about 5 min). These bursts reached a maximum intensity of only about 40 per cent above the persistent flux level. Like previous long bursts observed from GX 17+2, the long burst showed little softening during its decay, and it is difficult at first glance to classify it as either a type 1 or a type 2 burst. Following the recent results of van Paradijs and Lewin (1986) the authors have made a time-dependent spectral analysis of these bursts. The analysis provides a consistent description of the intensity and spectral variations during the burst in terms of the luminosity (and temperature) variation of a hot blackbody (or blackbody-like) emitter. Outside the burst the blackbody component contributes about 40 per cent to the persistent emission. This result probably resolves the previous ambiguity in the classification of bursts from GX 17+2 as type 1 or type 2, and indicates that, in spite of their unusual properties, these bursts are due to thermonuclear flashes.
