Quasi‐periodic Occultation by a Precessing Accretion Disk and Other Variabilities of SMC X‐1
Quasi‐periodic Occultation by a Precessing Accretion Disk and Other Variabilities of SMC X‐1
We have investigated the variability of the binary X-ray pulsar SMC X-1 in data from several X-ray observatories. We confirm the ~60 day cyclic variation of the X-ray flux in the long-term monitoring data from the RXTE and CGRO observatories. X-ray light curves and spectra from the ROSAT, Ginga, and …
