Spectral Broadening of Radiation from Relativistic Collapsing Objects
V. Frolov, K. Kim, H. K. Lee
Abstract
We study light curves and the spectral broadening of the radiation emitted during the finite interval of time by a surface of a collapsing object. We study a simplified model of monochromatic radiations from a spherical surface which is assumed to be falling freely. We discuss the possible way how to infer the physical parameters, such as the mass and radii of emission, from the light curves and spectral broadenings.
