  The particularly abundant presence of blue straggler stars (BSS) in Galactic
open clusters offers favorable conditions for detailed studies on the
statistical properties and the origin of the blue straggler population. With
the help of Gaia DR3, the number of identified open clusters continuously
increases, and the determination of star cluster members is more reliable. We
performed a more thorough search for BSS in newly found open clusters based on
Gaia data. We implemented a uniform membership determination for over one
thousand newly identified open clusters with larger sky coverage based on the
astrometric and photometric data from Gaia DR3. The membership probabilities of
stars were assigned by the pyUPMASK algorithm. Then we estimated the physical
parameters of these clusters by isochrone fitting on their CMDs and picked out
BSS in the specific region of these CMDs. We identified 138 BSS that had not
been reported before in 50 open clusters. Compared with recent catalogs that
present more than 1500 BSS in 339 open clusters, our new catalog increased the
number of BSS in Galactic open clusters by about 10%, and the number of open
clusters with BSS by nearly 17%. In the future, more accurate abundance
measurements are anticipated to better probe the origin of BSS in open
clusters.
