NAZOV / TITLE :

The evolutionary status and classification of selected neglected
eclipsing binaries observed with TESS.

ABSTRAKT / ABSTRACT :

Many eclipsing binaries lack reliable classifications and determinations
of their orbital elements and absolute parameters, such as the masses,
radii and luminosities of their components. Using a catalogue of eclipsing
binaries published by Avvakumova et al. (2013), we identified approximately
250 relatively bright systems with unreliable and/or missing data. Based
on further selection criteria, 102 eclipsing systems with different properties
were selected. To obtain the missing information, we used archival data from
two space missions: TESS (Transiting Exoplanet Survey Satellite) and Gaia.
The results and the most interesting cases are presented and discussed.
