Abstract

In this study, we have used the Gaia Third Data Release (Gaia DR3) to investigate an intermediate-age open cluster Collinder 74. We have identified 102 probable cluster members by considering stars with a membership probability exceeding 0.5 and located within the designated confinement radius. The mean proper-motion components of Collinder 74 are estimated as (𝜇𝛼 cos 𝛿, 𝜇𝛿) = (0.960 ± 0.005, −1.526 ± 0.004) mas yr−1 . We detected previously confirmed four blue straggler stars which show flat radial distribution. Colour excess, distance, and age of the cluster were estimated simultaneously by fitting PARSEC isochrones to the observational data on Gaia based colour magnitude diagram. These values were derived as 𝐸(𝐺BP − 𝐺RP) = 0.425 ± 0.046 mag, 𝑑 = 2831 ± 118 pc and 𝑡 = 1800 ± 200 Myr, respectively. The mass function slope was estimated as Γ = 1.34 ± 0.21 within the mass range 0.65 ≤ 𝑀/𝑀⊙ ≤ 1.58 which is well matched with that of Salpeter. Stellar mass distribution indicated that the massive and most likely stars are concentrated around the cluster center. The total mass of the cluster was found to be 365 𝑀/𝑀⊙ for the stars with probabilities 𝑃 > 0. Galactic orbit integration shows that the Collinder 74 follows a boxy pattern outside the solar circle and is a member of the thin-disc component of the Galaxy.
