Description
Accretion disk winds in compact objects in low-mass X-ray binaries, suggested by the blue-shifted absorption lines in spectroscopic data, are important phenomena to address the understanding of the physics of AGN feedback. However, the driving mechanisms of the winds are unclear. To tackle this, we build a comprehensive model for X-ray spectra, where the detail line profiles are simulated by Monte-Carlo radiation transfer (MCRT), whose input density/velocity fields are done by the radiation hydrodynamics code. Our models show that the observed spectra are well described by the winds launched at a larger radius driven by radiative heating/acceleration. We also show the new result of high-resolution spectroscopy by microcalorimeters onboard XRISM.
