Research Abstract

Radiation from compact objects, such as black holes, is known to exhibit rapid variations, though its origin remains to be an open question. In this project we construct a high-speed spectroscopy system and perform high-optical speed spectroscopy of close binary systems, aiming at detecting rapid color changes, that is, an evidence of particle acceleration. On schedule we have completed the system, attached it to the "Kanata" telescope at the Hiroshima Observatory, and observed cataclysmic variables, finding some interesting variations. We also perform radiation-magnetohydrodynamic simulations of accretion flow and are trying to interpret our observational findings.
