The aim of the research is to study the cometary activity in exoplanet systems and debris disks and to improve the detection methods of exocomets. The aim of the second step of the project is the application of machine learning methods for morphological classification of transit features. Searching for asymmetric transits in the TESS database and their modeling in order to assess the physical parameters of exocomets and the transit geometric circumstances. Research methods: mathematical methods of data filtering, modeling, data processing and data analysis, machine learning. Results and its novelty: the work has been started to apply the machine learning methods for the classification of transit phenomena found during the monitoring the TESS database. Searching for exocomet transits in the TESS database by classical methods has been continued. A number of events that are candidates for transits due to the passage of exocomets on the stars’ disks have been identified. Modeling of exocomet transits in the β-Pictoris star system was carried out, both known and found by us in the course of the project, was carried out.  Product Description popup.authors Vasylenko Maksym Yu.
