Gaia DR3 mission has identified and provided about 440,000 binary systemswith orbital solutions, offering a valuable resource for searching binariesincluding a compact component. By combining the Gaia DR3 data with radialvelocities (RVs) from the LAMOST spectroscopic survey, we identify three widebinaries possibly containing a compact object. For two of these sources with amain-sequence companion, no obvious excess is observed in the blue/red band ofthe Gaia DR3 XP spectra, and the LAMOST medium-resolution spectra exhibit clearsingle-lined features. The absence of an additional component from spectraldisentangling analysis further suggests the presence of compact objects withinthese systems. On the other hand, the visible star of the third source is astripped giant star. In contrast to most binaries including stripped stars, noemission line is detected in the optical spectra. The unseen star couldpotentially be a massive white dwarf or neutron star, but the possibility of anF-type dwarf star scenario cannot be ruled out. An examination of about tenbinaries containing white dwarfs or neutron stars using both kinematic andchemical methods suggest most of these systems are located in the thin disk ofthe Milky Way.
