cds-question@unistra.frmilky-way-galaxyopen-star-clustersvisible-astronomytrigonometric-parallaxproper-motionsradial-velocityWe report 541 new open cluster candidates in Gaia EDR3 through revisit the cluster results from an earlier analysis of the Gaia DR2, which revealed near a thousand open cluster candidates in the solar neighbourhood (mostly d<3kpc) reside at Galactic latitudes |b|<20 degrees. The subsequent comparison with lists of known clusters shows greatly increases of the cluster samples within 2kpc from the sun. We assign membership probabilities to the stars through the open source pyUPMASK algorithm, and also estimate the physical parameters through isochrone fitting for each candidate. Most of the new candidates show small total proper motion dispersion, clear features in the color-magnitude diagrams. Besides, the metallicity gradient of the new candidates is consistent with the literature, but it present a deeper gradient in young subset. The discovery of the new objects shows that the open cluster samples in Gaia data are still not complete, and more discoveries are expected in the future
