A search for additional bodies in short period eclipsing binary stars

We describe here the formulation of our search for additional bodies in fifteen short period eclipsing binary stars and some results obtained by now. We intended to use two methods: transits across the surface of one or both stars (in order to detect planets) in the binary and a timing of eclipses of central binary stars (that can indicate the presence of a stellar mass body in the system). Observations were carried out using ground based photometry with 50-60 cm telescopes in 2013-2017. Until now no transits had been detected in our data. But at the same time we found several candidates for additional bodies in four systems. Further data processing will be performed.
