Title: Case Studies of Exocomets in the System of HD 10180,
Abstract: The aim of our study is to investigate the dynamics of possible comets in the
HD 10180 system. This investigation is motivated by the discovery of exocomets
in various systems, especially $\beta$ Pictoris, as well as in at least ten
other systems. Detailed theoretical studies about the formation and evolution
of star--planet systems indicate that exocomets should be quite common. Further
observational results are expected in the foreseeable future, in part due to
the availability of the Large Synoptic Survey Telescope. Nonetheless, the Solar
System represents the best studied example for comets, thus serving as a prime
motivation for investigating comets in HD 10180 as well. HD 10180 is strikingly
similar to the Sun. This system contains six confirmed planets and (at least)
two additional planets subject to final verification. In our studies, we
consider comets of different inclinations and eccentricities and find an array
of different outcomes such as encounters with planets, captures, and escapes.
Comets with relatively large eccentricities are able to enter the inner region
of the system facing early planetary encounters. Stable comets experience
long-term evolution of orbital elements, as expected. We also tried to
distinguish cometary families akin to our Solar System but no clear distinction
between possible families was found. Generally, theoretical and observational
studies of exoplanets have a large range of ramifications, involving the
origin, structure and evolution of systems as well as the proliferation of
water and prebiotic compounds to terrestrial planets, which will increase their
chances of being habitable.
