TADROSS, A. L.  y  ELHOSSEINY, E. G.. The Principal Astrophysical Parameters of The Open Clusters Gulliver 18 And Gulliver 58 Determined Using Gaia EDR3 Data. Rev. mex. astron. astrofis [online]. 2022, vol.58, n.2, pp.387-393.  Epub 20-Mar-2023. ISSN 0185-1101.  https://doi.org/10.22201/ia.01851101p.2022.58.02.17.

A photometric and astrometric study of the two open star clusters Gulliver18 and Gulliver58 was carried out for the first time using the early third data release of the Gaia space observatory (Gaia-EDR3). By studying the proper motions, parallaxes, and color-magnitude diagrams of the two clusters, we determined their actual cluster membership. Therefore, ages, color excesses, and heliocentric distances of the clusters could be determined. The luminosity function, mass function, total mass, mass segregation, and relaxation time of Gulliver18 and Gulliver58 were estimated as well.
