Abstract

V originále

Our research is related to observing unstudied Galactic open clusters in Ultraviolet and analyzing their photometric data. We observed via the DK1.54 meter telescope in Chile and the 2.15m at CASLEO telescope in Argentina in the Ultraviolet filter because it is the best way of observing the interstellar reddening. The reddening is independent of the age and metallicity. After the observation, we did PSF photometry of all cluster fields. Then, matched the stars with Gaia Data Release 3. Afterwards, plotted the color-color diagram of Gaia magnitudes with our Ultraviolet magnitude. Then, we fitted isochrones to all cluster sequences. Our goals are: 1) Are these new open clusters that we observed with DK1.54 and CASLEO telescopes real open clusters or not? 2) Estimate the reddening for all our observed clusters in difefrent passbands. With these data, a first homogeneous census of unstudied open clusters in the Milky Way using Ultraviolet photometry can be derived and compared to the literature.
