The disintegrating old open cluster Czernik 3
Listed in IVOA Registry (Virtual Observatory)
We have performed a detailed analysis of the Czernik 3 (Cz3) open cluster by using deep near-infrared photometry taken with TIRCAM2 on the 3.6m Devasthal optical telescope along with the recently available high-quality proper motion data from the Gaia DR2 and deep photometric data from Pan-STARRS1.
Description
The cluster has a highly elongated morphology with fractal distribution of stars. The core and cluster radii of the cluster are estimated as 0.5 and 1.2pc, respectively.
We have identified 45 stars as cluster members using the Gaia proper motion data. The distance and age of the cluster are found to be 3.5+/-0.9kpc and 0.9^+0.3^_-0.1_Gyr, respectively. The slope of the mass function '{Gamma}' in the cluster region, in the mass range ~0.95<M/M_{sun}_<2.2, is found to be -1.01+/-0.43.

The cluster shows the signatures of mass segregation and is dynamically relaxed (dynamical age = 10Myr). This along with its small size, big tidal radius, low density/large separation of stars, and elongated and distorted morphology indicates that the Cz3 is a loosely bound disintegrating cluster under the influence of external tidal interactions.
