  abstract     = {{The system around the star Beta Pictoris is often referred to as the poster child of exoplanet research. However, the planetary system contains many more interesting components inside its large protoplanetary disks. When examining the stellar spectrum, long-lasting absorption lines near the Ca II lines of the star have been observed. While these absorption lines resemble those of transiting exocomets, the duration of the absorption lines is significantly longer than the transit time of a single comet. There is instead a stream of comets. This stream would have to have originated from the same source in order to end up on the same orbit, and one possibility is that larger comets are pulled apart by tidal interactions with the star and planet (Tidal Disruption Events).

The aim of this project is to examine the characteristics of comet streams generated through tidal disruption with simulations using the N-body integrator REBOUND. After performing 25 simulations, totaling 3025 massless particles, 110 streams of exocomets were generated, out of which 103 were generated by the star. The coherence time of the streams consistently exceeded a year, and the transit time of an entire stream ranged from less than a month up to a year. The streams generated by the star were on highly eccentric orbits with periods below one year and periastron distance within the sublimation limit, while the streams generated by The system around the star Beta Pictoris is often referred to as the poster child of exoplanet research.

The streams generated by the star were on highly eccentric orbits with periods below one year and periastron distance within the sublimation limit, while the streams generated by $\beta$ pic c evolved to more closely resemble the disk population.

The findings of this project shows that tidal disruptions are a valid way to generate exocomet streams, and that streams generated by the star resemble what was expected based on observations of the system. ß pic c evolved to more closely resemble the disk population.
