A grid of binary evolution models are calculated for the study of a blue straggler(BS) population in intermediate age(log Age = 7.85 8.95) star clusters.The BS
We made model fitting to the mid-to-far infrared spectral energy distributions (SEDs) for different categories of galaxies in the main extragalactic field of th
We present metallicities and radial velocities for five old open clusters (NGC 6791,NGC 2420,NGC 2682,NGC 2158,and NGC 7789)using data from the seventh public d
