Exploring Bochum 2: A Deep Optical Photometric Study.
Indian astronomers have conducted deep optical photometric observations of the open cluster Bochum 2 using the 1.3m Devasthal Fast Optical Telescope (DFOT). The study found that Bochum 2 has a radius of 3.6 light years, a reddening of 0.8 mag, and is located approximately 12,400 light years away from Earth. The cluster's dynamical age was estimated to be 8-14 million years, while the age of the most massive stars in Bochum 2 was calculated to be about 5 million years. The study also found the presence of an excess number of low-mass stars in Bochum 2, indicating the effect of mass segregation.
