Extrasolar Planets in Binary Systems (Statistical Analysis)

Abstract

During the last decades, searching for extrasolar planets was growing rapidly, and about 3869 exoplanets were discovered using various detection methods. In this work, we present a statistical analysis for these known exoplanets up to date provided by NASA Exoplanet Archive. In addition, we classify them depending on the type of the host stars' type; single star, and binary or multiple systems. Focusing on the exoplanets in binary system, we determine the common type of the stability orbit of the host binary system, and the probable mass ratio of the system to host a minimum one exoplanets. Moreover, we clarify the number of the companion planets for different systems.
