X-ray binaries offer a unique opportunity to study accretion in relatively clean environments and on human-accessible timescales, much shorter than those typical of AGN and quasars. Over the past few decades, the coupling between accretion and ejection processes in these systems has been extensively investigated, primarily through X-ray and radio continuum observations. More recently,...

Optical spectroscopy has become a powerful probe of accretion and ejection in outbursting low-mass X-ray binaries. Over the past decade, outflow signatures once confined to X-rays have been routinely identified at optical, near-infrared, and ultraviolet wavelengths, establishing a new framework for investigating accretion-disc winds and their connection to the accretion flow. Canonical optical...

Ultra-Compact X-ray Binaries (UCXBs) are a subclass of neutron star low-mass X-ray binaries (NS-LMXBs) characterized by very short orbital periods ($P<80$ min) and compact system sizes, making them ideal systems for probing the properties of accretion disks, in particular the structure and kinematics of winds and outflows. The detection of wind features in X-ray spectra is not always...
