摘要

The structure and emission properties of supercritical accretion disks have been well-investigated both analytically and numerically. Due to the existence of an optically thick wind, however, we cannot see the surface of the naked supercritical disks without wind, but observe the apparent photosphere formed in the wind. Using a simple wind model, we examined the observational appearance and expected spectra of the wind-disk system. We confirmed that the apparent photosphere in the wind is certainly located high above the disk surface. We also found that the comoving spectra of the apparent photosphere resembles the characteristic flat spectral energy distribution of the supercirtical disks, as long as the radiative flux is conserved in the wind, although the observed spectra remarkably depends on the velocity distribution on the apparent photosphere. We further examined the inclination angle dependence, and calculated the apparent luminosity of the wind-disk system. We found that the apparent luminosity distribution well-reproduces the observational trend of the luminosity function of the observed ultra-luminous X-ray sources.
