Spectral and temporal properties of X-ray emission from the ultra-luminous source X-9 in M81
V. La Parola, G. Fabbiano, D. W. Kim +1
We have analysed the spectra and the variability of individual X-ray sources in the M-81 field using data from the available ROSAT-PSPC and ROSAT-HRI observations of this nearby sp…

Spectra and evolution of two X-ray sources in M81
V. La Parola, G. Fabbiano, D. W. Kim +1
We analyzed the spectral and temporal features of X-ray sources in M81 using data from the relevant ROSAT-PSPC/HRI observations. We discuss the main features of the point-like nucl…
