英文摘要The high-precision Gaia Data Release 3 (DR3) enables the discovery of numerous open clusters (OCs) in the Milky Way, providing an excellent opportunity to search for blue straggler stars in OCs and investigate their formation and evolution in these environments. Using the member stars from literature OC catalogs, we visually inspected the color-magnitude diagram (CMD) of each cluster and selected cluster candidates that potentially host blue stragglers. We then reassessed cluster memberships using the pyUPMASK algorithm with Gaia DR3 and performed isochrone fitting to derive physical parameters for each cluster, including age, distance modulus, mean reddening, and metallicity. Finally, we empirically identified straggler stars based on their positions relative to the best-fitting isochrone, zero-age main sequence, and equal-mass binary sequence on the CMD. In total, we identified 272 new straggler stars in 99 OCs, comprising 153 blue stragglers, 98 probable blue stragglers, and 21 yellow stragglers. Compared to the reported blue straggler catalogs based on earlier Gaia data, our results increase the number of OCs with stragglers in the Milky Way by 22.2%, and the total number of blue stragglers by 11.2%.
