Title

UNDERSTANDING EVOLUTION OF DISK WIND IN BLACK HOLE X-RAY BINARIES

Abstract

We propose ToO observations of a Galactic transient black hole X-ray binary with a high inclination angle, during the state transition. Resolve high-resolution spectroscopy in the state where wind absorption lines have been observed enables us to obtain essential wind parameters (such as density, velocity, and the ionization stage) to determine the wind structure and launching mechanism. We also search for weak absorption and emission lines from the wind (and also jets) in the states where significant lines have rarely been observed in X-rays. Moreover, we have organized a multi-wavelength monitoring campaign simultaneously with the XRISM observations, from which we can achieve the whole picture of the evolution of the accretion disk, disk wind, and jets.
