The Mechanism of the Optical Variability of Supersoft X-Ray Sources
Abstract
We present models of an accretion disk of Supersoft X-ray Sources (SSXSs) to compare with observations. Some SSXSs show peculior behavior in optical light curves. Especially SSXS RX J0513 in the Large Magellanic Cloud (LMC) is known for its quasi-periodic optical variability and X-ray on/off. Considering these observations, we examine three models of an accretion disk whose shape may affect the luminosity from the binary system. We, then, compare the computed spectra based on three models with observation. Two models give good agreements in the optical range, while the other does not. Using present models, we may predict the spectrum in currently unobservable wavelength.
