UOCS – XI. Study of blue straggler stars in open cluster NGC 7142 using UVIT/AstroSat

ABSTRACT We present a study of blue straggler stars (BSSs) of open cluster NGC 7142 using AstroSat/UVIT data and other archival data. Using a machine-learning-based algorithm, ML-MOC, on Gaia DR3 data, we find 546 sources as cluster members. Based on the location on the Gaia colour–magnitude diagram...
