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. 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.

Keywords : HRD, star clusters, Gaia DR3, stellar evolution
