Abstract: We have been conducting a spectroscopic survey of detached eclipsing binaries (DEBs) from the All-Sky Automated Survey (ASAS) database for more than three years. Thousands of high-resolution spectra of >300 systems have been secured, and used for radial velocity measurements and spectral analysis. We have found a zoo of multiple systems in our sample, such as spectroscopic triples and quadruples, visual binaries with eclipsing components, and circumbinary low-mass companions, including sub-stellar-mass candidates.
