We present $UBVI_c$ CCD photometry of the young open cluster Stock 8 with the aim to study the basic properties and star formation scenario in this region. The radius of the cluster is found to be $sim 6^{prime}$ ($sim 3.6$ pc) and the reddening within the cluster region varies from $E(B-V)=0.40$ to 0.60 mag. The cluster is located at a distance of $2.05 pm 0.10$ kpc. Using H$alpha$ slitless spectroscopy and 2MASS NIR data we identified H$alpha$ emission and NIR excess young stellar objects (YSOs), respectively. The colour-magnitude diagrams of these YSOs reveal that majority of these objects have ages between 1 to 5 Myr indicating a non-coeval star formation in the cluster. Massive stars in the cluster region reveal an average age of $le$ 2 Myr. In the cluster region ($r le 6^prime$) the slope of the mass function (MF), $Gamma$, in the mass range $sim 1.0 le M/M_odot < 13.4$ can be represented by a power law having a slope of $-1.38pm0.12$, which agrees well with Salpeter value (-1.35). In the mass range $0.3 le M/M_odot < 1.0$, the MF is also found to follow a power law with a shallower slope of $Gamma = -0.58pm 0.23$ indicating a break in the slope of the IMF at $sim 1 M_odot$. The slope of the $K$-band luminosity function for the cluster ($r le 6^prime$) is found to be $0.31pm0.02$, which is smaller than the average value ($sim$ 0.4) obtained for embedded star clusters. A significant number of YSOs are distributed along a Nebulous Stream towards the east side of the cluster. A small cluster is embedded in the Nebulous Stream. The YSOs lying in the Nebulous Stream and in the embedded cluster are found to be younger than the stars in the cluster Stock 8. It appears that star formation activity in the Nebulous Stream and embedded cluster may be independent from that of Stock 8.
We present $UBVI_C$ 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 $sim$ 10 arcmin (2.9 pc). The interstellar extinction in the cluster
We present a comprehensive multi-wavelength study of the star-forming region NGC 1893 to explore the effects of massive stars on low-mass star formation. Using near-infrared colours, slitless spectroscopy and narrow-band $Halpha$ photometry in the cl
Different environmental conditions can play a crucial role in determining final products of the star formation process and in this context, less favorable activities of star formation are expected in the external regions of our Galaxy. We studied the
Most stars are born in rich young stellar clusters (YSCs) embedded in giant molecular clouds. The most massive stars live out their short lives there, profoundly influencing their natal environments by ionizing HII regions, inflating wind-blown bubbl
In this work we have carried out an in-depth analysis of the young stellar content in the W3 GMC. The YSO population was identified and classified in the IRAC/MIPS color-magnitude space according to the `Class scheme and compared to other classificat
