Abstract : We attempt to study the enigmatic, bluer stellar systems that lie along the apparent extension of main sequence of the cluster M67. These non-standard stellar systems are known as blue-stragglers. Many theories were proposed to explain the position of these stragglers in CMD , i.e., the increase in temperature of these systems. We have obtained the high-resolution spectra of blue stragglers in the open cluster M67. The aim is to verify the binary nature of the stragglers: 0131 and 0081, by measuring the radial velocities of these stragglers at different epochs.
