Gaia astrometric and photometric study of open clusters Dolidze 18 & Ruprecht 70
Abstract
Open star clusters (OCs) are stellar systems that originated under the same astrophysical environments, at the same distance, with identical ages, original chemical compositions, and various masses. These objects are crucial to explaining the Milky Way Galaxy’s structure and evolution (cf. Gilmore et al. (2012); Moraux. (2016)). Our data on OCs came from well-known global catalogs and databases, such as Dias et al. (2002, 2014) and Webda (https://webda.physics.muni.cz/navigation.html), which provide all the knowledge required to conduct accurate studies of such objects.
