Abstract

We present an investigation of the open cluster Trumpler 2 using Gaia DR3 photometric, astrometric and spectroscopic data. 92 stars were identified as likely members of the cluster, with membership probabilities greater than 0.5. The mean proper-motion components of the cluster are derived as (𝜇𝛼 cos 𝛿, 𝜇𝛿)=(1.494 ± 0.004, −5.386 ± 0.005) mas yr−1 . By comparing the Gaia based colour-magnitude diagram with the PARSEC isochrones scaled to 𝑧 = 0.0088, age, distance modulus and reddening are simultaneously estimated as 𝑡 = 110±10 Myr, 𝜇 = 10.027±0.149 mag and 𝐸(𝐺BP −𝐺RP) = 0.452±0.019 mag, respectively. The total mass of the cluster is estimated as 162 𝑀/𝑀⊙ based on the stars with membership probabilities 𝑃 > 0. The mass function slope is derived to be Γ = 1.33 ± 0.13 for Trumpler 2. This value is in a good agreement with that of Salpeter. Galactic orbit analyses show that the Trumpler 2 orbits in a boxy pattern outside the solar circle and belongs to the young thin-disc component of the Galaxy.
