| Abstract | We present UBV IC CCD photometry of the young open cluster Be 59 with the aim to study the star formation scenario in the cluster. The radial extent of the cluster is found to be ∼ 10 arcmin (2.9 pc). The interstellar extinction in the cluster region varies between E(B − V ) ≃ 1.4 to 1.8 mag. The ratio of total-to-selective extinction in the cluster region is estimated as 3.7 ± 0.3. The distance of the cluster is found to be 1.00 ± 0.05 kpc. Using near-infrared colours and slitless spectroscopy, we have identified young stellar objects (YSOs) in the open cluster Be 59 region. The ages of these YSOs range between < 1 Myr to ∼ 2 Myr, whereas the mean age of the massive stars in the cluster region is found to be ∼ 2 Myr. There is evidence for second generation star formation outside the boundary of the cluster, which may be triggered by massive stars in the cluster. The slope of the initial mass function, Γ, in the mass range 2.5 < M/M⊙ ≤ 28 is found to be −1.01± 0.11 which is shallower than the Salpeter value (-1.35), whereas in the mass range 1.5 < M/M⊙ ≤ 2.5 the slope is almost flat. The slope of the K-band luminosity function is estimated as 0.27 ± 0.02, which is smaller than the average value (∼0.4) reported for young embedded clusters. Approximately 32% of Hα emission |
