| Popis: | We have performed a detailed analysis on the Teutsch 76 (T76) open cluster using the deep near-infrared (NIR) observations taken with the TANSPEC instrument mounted on the 3.6m Devasthal Optical Telescope (DOT) along with the recently available high quality proper motion data from the {\it Gaia} data release 3 and deep photometric data from Pan-STARRS1 survey. We have found that the T76 cluster is having a central density concentration with circular morphology, probably due to the star formation processes. The radius of the T76 cluster is found to be 45$^{\prime}{^\prime}$ (1.24 pc) and 28 stars within this radius were marked as highly probable cluster members. We have found that the cluster is located at a distance of $5.7\pm1.0$ kpc and is having an age of $50\pm10$ Myr. The mass function slope ($\Gamma$) in the cluster region in the mass range $\sim$0.75$<$M/M$_\odot$$<$5.8 is estimated as $-1.3\pm0.2$, which is similar to the value `-1.35' given by \citet{1955ApJ...121..161S}. The cluster is not showing any signatures of mass-segregation and is currently undergoing dynamical relaxation. Comment: Accepted for publication in Journal of Astrophysics and Astronomy |
