Binary stars play a vital role in astrophysical research, as the
majority of stars are in binaries. I will discuss the photometric
identification of binaries in open clusters along with their cluster
membership. The binary fraction of open clusters ranges from 0.2 to 0.6
and it varies with the mass of the primary stars. I will summarise a few
studies focused on the evolution and detection of peculiar binary
products such as blue stragglers and blue lurkers using Gaia and UVIT
data. I plan to also present our ongoing work regarding the cluster
dynamics, specifically signatures of rotation and expansion in open
clusters.
