| 内容記述 | Recent Rosat position sensitive proportional counter (PSPC) observations demonstrate the presence of a compact source of hard X-ray emission centers on the peculiar star, eta Carinae. These observations show a change in the hard band counting rate of a factor of 2 in a 4-month interval. The Rosat high resolution imager (HRI) observations which span the PSPC observations also reveal a variable source of X-ray emission centered in eta Carinae. Therefore, the strong variability which is a characteristic of eta Carinae in radio, infrared and visible wavebands is also observed at X-ray energies. The X-ray light curve of eta Carinae is examined using data from various astronomical data bases. |
