| 内容記述 | Observations with the MIT experiment on the OSO-7 have led to the discovery of an X-ray source, GX 339-4, which varies in intensity by at least a factor of 60 over hundreds of days but shows no evidence of periodic behavior or abrupt intensity changes on time scales from 3 minutes to 13 days. The observations show intense high states, low states with spectra consistent with increased absorption, and off states, when no statistically significant signal is observed. The behavior is unlike that of any previously reported X-ray source. |
