Purpose of work: detection and studying of the comet-like activity within exoplanet systems; estimation of the exocomet physical properties. Research methods: frequency analysis of the photometric time series (light curves) observed with the TESS orbital telescope, modeling the dust distribution in exocomet comae, retrieving transit profiles in the stellar light curves, application of machine learning methods on the TESS light curves. Results and novelty: 5 new exocomets were discovered in the beta Pictoris system; for the first time, we estimate the physical parameters of exocometary dust based on the properties of known comets in the Solar system, the machine learning software package was created for the analysis of morphological features in the light curves of stars.   Product Description popup.authors Vasylenko Maksym Yu.
