Zusammenfassung: | The results are given of observations of fuorlike outbursts of the objects Sugano and Chanal in the Orion association. Light curves have been constructed, and the outburst amplitudes and color indices have been determined. It was shown that the object Sugano exhibits the behavior of both an Orion variable and a flare star. Estimates of /delta//prime/ and /delta/ show that they are of the same order as in the case of furors. It is conjectured that although outflow is observed in the case of many nonstationary stars there is in the considered case an intensification of the outflow, possibly at the same velocities, of the matter that forms the envelope. The luminosity of P Cyg before its outburst is determined. |
