Abstract
Up to now, more than 500 extra-solar planets have been discovered. Many
of these extrasolar systems consist of one star and only one giant
planet. However, recently more and more different types of systems have
become known, including also extrasolar planets in binaries. In our
study, we will concentrate on such systems, since a large percentage of
all G-M stars are expected to be part of binary or multiple stellar
systems. Therefore, these kinds of systems are worthy of investigation
in detail. In particular, we will concentrate on planets in P-Type
motion, where the planet orbits around both stars. During the last few
years, four such systems (NN Ser, HW Vir, HU Aqr and DP Leo) have been
discovered. In our study, we performed dynamical studies for three
multi-planetary systems in binaries (NN Ser, HW Vir, HU Aqr), and
compared simulated eclipse timing variations (ETV) to current
observational data.
