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.
