| Abstract : | The presence of gaps or regions of small numbers of stars in the main sequence of the Hertzsprung Russell Diagram (HRD) of star clusters has been reported in literature. This is interesting and significant as it could be related to star formation and/or rapid evolution or instabilities. We selected a sample of nine clusters as clusters with confirmed gaps from literature. In this paper, using Gaia DR3 photometry and confirmed membership data, we explore the HRD of nine open clusters with reported gaps, identify them and assess their importance and spectral types. We use the $\chi^2$ test to find the significance of the gaps. We compare the spectral types of earlier detections and find that they agree with our present results. |
